Difference Between Descriptive and Experimental Research

The main difference between descriptive and experimental research is that the descriptive research describes the characteristics of the study group or a certain occurrence while the experimental research manipulates the variables to arrive at conclusions.

Descriptive research and experimental research are two types of research people use when doing varied research studies. Both these research types have their own methods that facilitate the researcher to gain maximum outcomes.

What is Descriptive Research

Descriptive research is a type of research that studies the participants that take part in the research or a certain situation. Descriptive research does not limit to either of quantitative or qualitative research methodologies, but instead, it uses elements of both, often within the same study. Therefore, a descriptive researcher often uses three major ways to collect and analyse the data. They are observations, case studies and surveys.

Descriptive studies are aimed at finding out “what is,” therefore, observational and survey methods are frequently used to collect descriptive data (Borg & Gall, 1989). Thus, the main focus of descriptive research is to answer the question ‘what’ with concern to the study group. Moreover, descriptive research, primarily concerned with finding out “what is,” that might be applied to investigate the particular study group or the situation. Therefore,  descriptive research does not give answers to the cause and effect of the particular occurrence that is studied. 

Therefore, descriptive research assists to make specific conclusions regarding situations such as marketing products according to the needs of the customers, to estimate the percentages of units in a specified population according to a certain behaviour, etc. Some examples of descriptive researches include population census and product marketing surveys.

What is Experimental Research?

Experimental research is the research study where the scientist actively influences something to observe the consequences. Experimental research uses manipulation and controlled testing to understand causal processes. Therefore, in this type of research, the researcher manipulates one given variable and controls the others to come to a conclusion.

This type of research typically includes a hypothesis, a variable that can be manipulated, measured, calculated and compared. Eventually, the collected data and results will either support or reject the hypothesis of the researcher. Therefore, one could call this research type as a true experiment.

In this research type, the researcher manipulates the independent variables such as treatment method and teaching methodology, and measures the impact it has on the dependent variables such as cure and student comprehension in order to establish a cause-effect relationship between these two variables. Therefore, this research type can answer the questions of cause, effect and results, thus, making it possible to make hypothetical assumptions based on the gathered data. Therefore, unlike descriptive research which answers’ what is’, experimental research answers the question ‘what if’. Therefore, usually, this type of research uses quantitative data collection methodology.

Evidently, this type of research is mostly conducted in a controlled environment, usually a laboratory. Experimental research is mostly used in sciences such as sociology and psychology, physics, chemistry, biology, medicine, etc.

Descriptive research is the type of research where characteristics of the study group or a certain occurrence are described while experimental research is the research type that manipulates variables to come to a conclusion. This is the main difference between descriptive and experimental research.

Descriptive research is useful in gathering data on a certain population or a specific occurrence while experimental research is useful in finding out the cause-effect of a causal relationship, correlation etc

The aim of the descriptive research is to describe the characteristics of the study group, thus answering the question ‘what is’ while the aim of the experimental research is to manipulate the given variables so as to support or reject the assumed hypothesis. Hence it answers the question ‘what if’.

Type of Studies

Descriptive research typically includes sociological and psychological studies while experimental research typically includes forensic studies, biological and other laboratory studies, etc.

Data Collection

Descriptive research uses both qualitative and quantitative methodologies while experimental research primarily uses quantitative methodology.

Descriptive and experimental research are two significant types of research. Both these research types are helpful in analysing certain occurrences and study groups. The main difference between descriptive and experimental research is that descriptive research describes the characteristics of the research subject while the experimental research manipulates the research subject or the variables to come to a conclusion. Similarly, descriptive research answers the question ‘what is’ while experimental research answers the question ‘what if’.

Descriptive Research Design – Types, Methods and Examples

Table of Contents

Descriptive research design is a crucial methodology in social sciences, education, healthcare, and business research. It focuses on describing characteristics, behaviors, or phenomena as they exist without influencing or manipulating the study environment. This type of research provides a snapshot of specific conditions or attributes, making it an essential approach for understanding trends, patterns, and relationships.

This article explores the concept of descriptive research design, its types, methods, and practical examples, providing a comprehensive understanding of its significance and applications.

Descriptive Research Design

Descriptive research design is a systematic methodology used to describe the characteristics of a population, event, or phenomenon. Unlike experimental research, which tests hypotheses, descriptive research answers “what,” “where,” “when,” and “how” questions. It does not examine causation but rather provides detailed information about existing conditions.

For example, a study describing the demographics of university students enrolled in online courses would employ a descriptive research design.

Importance of Descriptive Research Design

Descriptive research design is vital for:

• Establishing Baseline Data: It provides foundational knowledge to guide further research.
• Identifying Trends: It captures trends and patterns in behavior or phenomena.
• Informing Decision-Making: Organizations and policymakers rely on descriptive research for data-driven decisions.
• Understanding Complex Phenomena: It helps summarize and explain intricate systems or populations.

This design is widely used in fields such as sociology, psychology, marketing, and healthcare to generate valuable insights.

Types of Descriptive Research Design

1. cross-sectional research.

This type involves collecting data from a population or sample at a single point in time.

• Purpose: To describe the current status or characteristics of a population.
• Example: A survey measuring customer satisfaction with a product conducted in January.

2. Longitudinal Research

Longitudinal research collects data from the same subjects over an extended period, allowing researchers to observe changes and trends.

• Purpose: To identify patterns or changes over time.
• Example: Tracking changes in dietary habits among adolescents over five years.

3. Comparative Research

This design compares two or more groups or phenomena to highlight differences and similarities.

• Purpose: To explore variations and relationships between subjects.
• Example: Comparing stress levels between urban and rural employees.

4. Case Study Research

Case studies provide an in-depth examination of a single subject, group, or event.

• Purpose: To gain detailed insights into complex issues.
• Example: Analyzing the strategies of a successful startup to identify factors contributing to its growth.

Methods of Descriptive Research Design

1. surveys and questionnaires.

Surveys are the most common method in descriptive research, using structured or semi-structured questions to gather data.

• Easy to administer to large populations.
• Cost-effective.
• Example: Conducting a survey to determine customer preferences for smartphone features.

2. Observations

This method involves observing and recording behaviors, events, or conditions without interference.

• Provides real-time, naturalistic data.
• Useful for studying non-verbal behaviors.
• Example: Observing classroom interactions to analyze teacher-student dynamics.

Types of Observations

• Example: Observing a team meeting as a team member.
• Example: Watching interactions from a one-way mirror.

3. Secondary Data Analysis

Analyzing pre-existing data, such as government reports, academic articles, or historical records.

• Saves time and resources.
• Provides access to large datasets.
• Example: Using census data to describe population growth trends.

4. Interviews

Interviews involve asking open-ended or structured questions to gather in-depth information.

• Offers detailed insights and clarifications.
• Facilitates exploration of subjective experiences.
• Example: Conducting interviews with employees to understand workplace satisfaction.

5. Case Studies

Involves a deep dive into a specific instance to understand complex phenomena.

• Provides rich, contextualized data.
• Suitable for unique or rare cases.
• Example: Studying the response of a hospital to a public health emergency.

Steps in Conducting Descriptive Research

Step 1: define the research problem.

Clearly outline what you aim to describe and why it is significant.

• Example: “What are the shopping preferences of millennials in urban areas?”

Step 2: Select the Population or Sample

Identify the group you will study and ensure it represents the target population.

• Example: Randomly selecting 500 participants from an urban demographic.

Step 3: Choose the Data Collection Method

Select the most appropriate method based on the research problem and objectives.

• Example: Using a survey to collect data on customer satisfaction.

Step 4: Gather Data

Administer the survey, conduct interviews, or collect observations systematically.

Step 5: Analyze Data

Summarize findings using statistical or thematic analysis, depending on the nature of the data.

• Quantitative Data: Use statistical tools to identify trends.
• Qualitative Data: Use coding techniques to identify themes.

Step 6: Report Results

Present findings clearly and concisely, often with visuals like graphs, charts, and tables.

Examples of Descriptive Research Design

1. healthcare research.

Study: Assessing patient satisfaction in a hospital.

• Method: Distributing surveys to patients.
• Outcome: Identified areas of improvement in hospital services, such as wait times and staff communication.

2. Marketing Research

Study: Exploring customer preferences for eco-friendly packaging.

• Method: Conducting interviews and focus groups.
• Outcome: Revealed that consumers prefer biodegradable packaging and are willing to pay a premium for it.

3. Education Research

Study: Analyzing attendance patterns among college students.

• Method: Collecting secondary data from attendance records.
• Outcome: Found that attendance declines during midterm weeks, suggesting a need for academic support.

4. Social Research

Study: Examining the impact of social media usage on youth communication skills.

• Method: Observing and surveying participants.
• Outcome: Highlighted that frequent social media use correlates with reduced face-to-face communication skills.

Advantages of Descriptive Research Design

• Easy Implementation: Methods like surveys and observations are straightforward and cost-effective.
• Broad Applications: Can be used across disciplines to gather diverse data.
• Non-Intrusive: Describes phenomena without altering them, preserving natural behavior.
• Rich Data: Provides detailed insights into current states or conditions.

Limitations of Descriptive Research Design

• No Causal Relationships: It does not establish cause-and-effect relationships.
• Bias Potential: Surveys and observations may be subject to bias.
• Limited Scope: Restricted to describing existing conditions, limiting predictive capabilities.

Descriptive research design is an invaluable tool for understanding the characteristics and trends of a population or phenomenon. By employing methods such as surveys, observations, and secondary data analysis, researchers can gather rich, detailed insights that inform decision-making and guide further studies. While it does not explore causation, descriptive research provides a foundation for hypotheses and experimental research, making it a cornerstone of empirical inquiry.

Descriptive research involves gathering data to provide a detailed account or depiction of a phenomenon without manipulating variables or conducting experiments.

A scholarly definition is:

“Descriptive research is defined as a research approach that describes the characteristics of the population, sample or phenomenon studied. This method focuses more on the “what” rather than the “why” of the research subject.” (Matanda, 2022, p. 63)

The key feature of descriptive research is that it merely describes phenomena and does not attempt to manipulate variables nor determine cause and effect .

To determine cause and effect , a researcher would need to use an alternate methodology, such as experimental research design .

Common approaches to descriptive research include:

• Cross-sectional research : A cross-sectional study gathers data on a population at a specific time to get descriptive data that could include categories (e.g. age or income brackets) to get a better understanding of the makeup of a population.
• Longitudinal research : Longitudinal studies return to a population to collect data at several different points in time, allowing for description of changes in categories over time. However, as it’s descriptive, it cannot infer cause and effect (Erickson, 2017).

Methods that could be used include:

• Surveys: For example, sending out a census survey to be completed at the exact same date and time by everyone in a population.
• Case Study : For example, an in-depth description of a specific person or group of people to gain in-depth qualitative information that can describe a phenomenon but cannot be generalized to other cases.
• Observational Method : For example, a researcher taking field notes in an ethnographic study. (Siedlecki, 2020)

Descriptive Research Examples

1. Understanding Autism Spectrum Disorder (Psychology): Researchers analyze various behavior patterns, cognitive skills, and social interaction abilities specific to children with Autism Spectrum Disorder to comprehensively describe the disorder’s symptom spectrum. This detailed description classifies it as descriptive research, rather than analytical or experimental, as it merely records what is observed without altering any variables or trying to establish causality.

2. Consumer Purchase Decision Process in E-commerce Marketplaces (Marketing): By documenting and describing all the factors that influence consumer decisions on online marketplaces, researchers don’t attempt to predict future behavior or establish causes—just describe observed behavior—making it descriptive research.

3. Impacts of Climate Change on Agricultural Practices (Environmental Studies): Descriptive research is seen as scientists outline how climate changes influence various agricultural practices by observing and then meticulously categorizing the impacts on crop variability, farming seasons, and pest infestations without manipulating any variables in real-time.

4. Work Environment and Employee Performance (Human Resources Management): A study of this nature, describing the correlation between various workplace elements and employee performance, falls under descriptive research as it merely narrates the observed patterns without altering any conditions or testing hypotheses.

5. Factors Influencing Student Performance (Education): Researchers describe various factors affecting students’ academic performance, such as studying techniques, parental involvement, and peer influence. The study is categorized as descriptive research because its principal aim is to depict facts as they stand without trying to infer causal relationships.

6. Technological Advances in Healthcare (Healthcare): This research describes and categorizes different technological advances (such as telemedicine, AI-enabled tools, digital collaboration) in healthcare without testing or modifying any parameters, making it an example of descriptive research.

7. Urbanization and Biodiversity Loss (Ecology): By describing the impact of rapid urban expansion on biodiversity loss, this study serves as a descriptive research example. It observes the ongoing situation without manipulating it, offering a comprehensive depiction of the existing scenario rather than investigating the cause-effect relationship.

8. Architectural Styles across Centuries (Art History): A study documenting and describing various architectural styles throughout centuries essentially represents descriptive research. It aims to narrate and categorize facts without exploring the underlying reasons or predicting future trends.

9. Media Usage Patterns among Teenagers (Sociology): When researchers document and describe the media consumption habits among teenagers, they are performing a descriptive research study. Their main intention is to observe and report the prevailing trends rather than establish causes or predict future behaviors.

10. Dietary Habits and Lifestyle Diseases (Nutrition Science): By describing the dietary patterns of different population groups and correlating them with the prevalence of lifestyle diseases, researchers perform descriptive research. They merely describe observed connections without altering any diet plans or lifestyles.

11. Shifts in Global Energy Consumption (Environmental Economics): When researchers describe the global patterns of energy consumption and how they’ve shifted over the years, they conduct descriptive research. The focus is on recording and portraying the current state without attempting to infer causes or predict the future.

12. Literacy and Employment Rates in Rural Areas (Sociology): A study aims at describing the literacy rates in rural areas and correlating it with employment levels. It falls under descriptive research because it maps the scenario without manipulating parameters or proving a hypothesis.

13. Women Representation in Tech Industry (Gender Studies): A detailed description of the presence and roles of women across various sectors of the tech industry is a typical case of descriptive research. It merely observes and records the status quo without establishing causality or making predictions.

14. Impact of Urban Green Spaces on Mental Health (Environmental Psychology): When researchers document and describe the influence of green urban spaces on residents’ mental health, they are undertaking descriptive research. They seek purely to understand the current state rather than exploring cause-effect relationships.

15. Trends in Smartphone usage among Elderly (Gerontology): Research describing how the elderly population utilizes smartphones, including popular features and challenges encountered, serves as descriptive research. Researcher’s aim is merely to capture what is happening without manipulating variables or posing predictions.

16. Shifts in Voter Preferences (Political Science): A study describing the shift in voter preferences during a particular electoral cycle is descriptive research. It simply records the preferences revealed without drawing causal inferences or suggesting future voting patterns.

17. Understanding Trust in Autonomous Vehicles (Transportation Psychology): This comprises research describing public attitudes and trust levels when it comes to autonomous vehicles. By merely depicting observed sentiments, without engineering any situations or offering predictions, it’s considered descriptive research.

18. The Impact of Social Media on Body Image (Psychology): Descriptive research to outline the experiences and perceptions of individuals relating to body image in the era of social media. Observing these elements without altering any variables qualifies it as descriptive research.

Descriptive vs Experimental Research

Descriptive research merely observes, records, and presents the actual state of affairs without manipulating any variables, while experimental research involves deliberately changing one or more variables to determine their effect on a particular outcome.

De Vaus (2001) succinctly explains that descriptive studies find out what is going on , but experimental research finds out why it’s going on /

Simple definitions are below:

• Descriptive research is primarily about describing the characteristics or behaviors in a population, often through surveys or observational methods. It provides rich detail about a specific phenomenon but does not allow for conclusive causal statements; however, it can offer essential leads or ideas for further experimental research (Ivey, 2016).
• Experimental research , often conducted in controlled environments, aims to establish causal relationships by manipulating one or more independent variables and observing the effects on dependent variables (Devi, 2017; Mukherjee, 2019).

Experimental designs often involve a control group and random assignment . While it can provide compelling evidence for cause and effect, its artificial setting might not perfectly mirror real-worldly conditions, potentially affecting the generalizability of its findings.

These two types of research are complementary, with descriptive studies often leading to hypotheses that are then tested experimentally (Devi, 2017; Zhao et al., 2021).

Benefits and Limitations of Descriptive Research

Descriptive research offers several benefits: it allows researchers to gather a vast amount of data and present a complete picture of the situation or phenomenon under study, even within large groups or over long time periods.

It’s also flexible in terms of the variety of methods used, such as surveys, observations, and case studies, and it can be instrumental in identifying patterns or trends and generating hypotheses (Erickson, 2017).

However, it also has its limitations.

The primary drawback is that it can’t establish cause-effect relationships, as no variables are manipulated. This lack of control over variables also opens up possibilities for bias, as researchers might inadvertently influence responses during data collection (De Vaus, 2001).

Additionally, the findings of descriptive research are often not generalizable since they are heavily reliant on the chosen sample’s characteristics.

Difference between Descriptive Research and Experimental Research

Descriptive research is a method that focuses on detailing and explaining the characteristics of the subject being studied. It aims to answer questions about who, what, where, and when regarding the topic. On the other hand, experimental research is a scientific method used to test a theory or hypothesis by manipulating certain variables and observing the effects. This approach typically involves comparing an experimental group, which experiences the manipulation, with a control group that does not.

Descriptive Research

Descriptive research refers to research which describes a phenomenon or else a group under study and it is easy to do in social sciences due to manipulating variables. It is mainly useful for gathering data on a certain population, situations and events. Descriptive research is more towards collecting data and try to find out some insight out of that data using statistical analysis.

Example of descriptive research includes population census and product marketing surveys etc.

Experimental Research

Experimental research refers to research where the researcher manipulates the variable to come to an conclusion or finding and it is difficult to do in social sciences due to manipulating variables. It is useful in finding out the cause effect of a casual relationship and correlation. Experimental research is also do this same sort of analysis but also it always analyzes where the data of an experiment comes from.

Example of experimental research includes laboratory experiments.

Frequently Asked Questions on Descriptive Research vs Experimental Research – FAQs

1. what is the difference between descriptive correlational and experimental research.

Experimental research uses the independent variable to determine how it impacts the dependent variable, whereas descriptive correlational research simply describes the relationship between variables.

2. Is descriptive research qualitative or quantitative?

Descriptive research is typically classified as a sort of quantitative research, but qualitative research can also be utilized for descriptive purposes.

Exclusive Step by Step guide to Descriptive Research

Get ready to uncover the how, when, what, and where questions in a research problem

SHARE THE ARTICLE ON

Descriptive research and experimental research are both types of quantitative research. Quantitative research refers to the process of analyzing data in its numeric form. The objective of quantitative research is to examine social phenomena by collecting objective data. 

But there is a difference in the way descriptive research and experimental research are performed and the insights they deliver. We will explore how different the two research types are from one another. 

Before we jump into exploring descriptive vs experimental research, let’s define the two types.

What is Descriptive Research?

Descriptive research is a method to describe the demographics of the research variables. The demographics being “why, what, when, how” regarding the subject variable. Rather than limiting its approach to qualitative or quantitative, descriptive research is mostly observational. The reason being obvious, the variables are not influenced by any external variables and are observed to derive results from it. 

Descriptive research aims to statistically analyze the data collected through observations and surveys or case studies. The variables that are being observed are not controlled. As descriptive research digs out the patterns in the data, it helps researchers get future insights depending on the pattern. 

Methods of descriptive research:

• Observation – as the name suggests, this includes observing a variable in the study. It can be qualitative or quantitative in nature. Quantitative observations will give data that is numerically represented, whereas qualitative observations are more brief and long to analyze. 

For example, a company owner decides to implement new soft skill training among the employees. After the training is over he observes their speech and performance to figure out how effective the training program was. 

• Surveys – are the most common form of gathering feedback from the customers. This includes questionnaires regarding the topic which the responders will answer. It can be conducted online as well as offline and provides vast areas of channels to circulate them through. 

The main advantage of surveys is that it gets your hands on large amounts of data in a short time span. 

For example, a company owner wants to get feedback on a recent meeting. He will ask both open-ended as well as close-ended questions.

• Case studies – it is a deep study of an individual or group. It helps your frame hypothesis or theories. As it studies a natural phenomenon, researchers’ biases are avoided. Another reason is, a not-so-genuine responder. It would be unfair to study this responder who is a lot different from the general population and then generalize his results to the entire population. 

For example, a company owner studies an employee who travels far to come to the office. He may have a different experience with his traveling and its effect on his work, then the other employees. 

What is Experimental Research?

Experimental research is a scientific approach to dealing with two or more variables. It is basically an experiment conducted to bring out the cause-effect relationship between those variables. 

The experiment has two groups, a treatment group, and a control group. A researcher starts an experiment by keeping a problem statement in mind, and that includes a control variable. The treatment group undergoes the changes that the researcher wants to experiment with, and the control group doesn’t go through any treatment. At the end of the experiment, the researcher concludes how the independent variable affects the dependent variable when the course is changed. 

Experimental research aims to help you make meaningful insights out of the gathered data. It is useful in testing your hypothesis and making decisions about it. Experimental research is said to be successful when the manipulation of the independent variable brings about a change in the variable that is under study. 

Methods of experimental research:

Pre-experimental Design

It is sort of a dry run before a true experiment takes place. It studies one or two groups when they are put under the researcher’s treatment. This gives an idea of whether the treatment will solve the problem at hand or not. And if yes, then what is the right way to carry out the experiment when it actually takes place. 

The 3 kinds are; 

• One-shot case study research design
• One-group pretest-posttest research design
• Static group comparison 

[Related read: Pre-experimental Design ]

True-experimental Research Design  

It is hypothesis-testing research, which at the end of the study, will either support or refute the hypothesis. You can say this research is based on the foreground of the pre-experimental research. 

True experiments work on hypothesis testing with the help of independent and dependent variables, pre-testing and post-testing, treatment groups and control groups, and control variables. In addition to that, the samples are selected at random. 

For example, a teacher wants to know the average maths marks of her class. She will randomly select students to take the math test. 

Quasi-experimental Research  

It is similar to a true experiment but surely not the same. Just like true experiments, it also includes independent and dependent variables, pre-tests and post-tests, and treatment and control groups. 

The major difference is that it does not include randomization of samples and control variables. As a result of which, the participants are assigned to the experimental groups through a study that decides which participants to put in which experimental group. 

For example, a teacher wants to know how her class is doing in math, but more importantly, she wants to study the students that have an average score on a math test. So she will select only those students who have an average score in math. 

Descriptive Vs. Experimental Research

Definition .

Descriptive research is a method that describes a study or a topic. It defines the characteristics of the variable under research and answers the questions related to it. 

Whereas experimental research is a scientific approach to testing a theory or a hypothesis using experimental groups and control variables. 

Descriptive research will help you gather data on a subject or understand a population or group. 

Experimental research will help you establish a cause-effect relationship between two or more variables. 

Descriptive research aims towards studying the demographics related to a subject group. Experimental research aims to test hypotheses and theories, which include cause-effect variables. 

Descriptive research is sociological and psychological in nature. 

Experimental research uses a more scientific experimental approach to test the problems. 

Both of them differ in terms of external interventions. Descriptive research doesn’t face any, while experimental research has control variables. 

Method to gather data

In descriptive research , the study can be done by collecting qualitative and quantitative data types. 

But when it comes to experimental research , the data has to be quantitative in nature. 

Descriptive Vs. Experimental Research: Comparison Chart

Conclusion;

Despite falling under the types of quantitative research, descriptive research & experimental research differ significantly. This concludes all points of difference between the two research types. Next time you have to decide which research method, you can refer to this blog.

Wondering what will be the cost of conducting survey research using Voxco?

The main difference between the two is that – descriptive research is a qualitative or quantitative approach dedicated to observing the variable demographics under its natural habitat. While experimental research includes a scientific quantitative approach to test hypotheses and theories using control variables.

One example can be, a software company wants to develop a new shopping application. For that, they will observe the regular shopping experiences of the customers and what are current options they are preferring. Second example can be a researcher who wants to study social media experiences for different people belonging to different age groups.

Two things that will differentiate the two prime research methodologies can be:

• Descriptive research deals with observation and no external intervention while experimental research totally depends on the intervention. This intervention is caused by manipulation of the independent variable. 
• The use of descriptive research is done when you want to observe a certain group or an individual while experimental research is used when you have a theory and you want to test it out by experimenting on the variables. 

For instance, a new teaching strategy for math is tested for its effects. A random selection of students is done to undergo the special training for the subject. At the end of the training, results of the math tests are compared with the results before the training program. This will let the management know how effective the training is. 

• It has dependent and independent variables that give the cause-effect relationship between the variables. 
• It has pre-test and post-test study to compare the results of the experiment before the treatment and after the treatment. 
• Random sampling helps both the treatment group and control groups to have equal quality of participants. 

As descriptive research is an observational and experimental research is, well, experiment based, both have their own importance depending on the research problem. Use descriptive research when you just have to observe a group in its environment and develop an understanding on the subject. Use experimental research when you have to test a hypothesis or establish a cause-effect relation between two or more variables. 

Experimental research includes independent and dependent variables, it compares the pretest and post-tests while including randomization of samples and control variables. While non-experimental research doesn’t have randomization of the samples and it doesn’t manipulate the independent variables even if it is about establishing causal relationships between the variables.

A comparison of descriptive research and experimental research

Quantitative research refers to data present in numeric form. When collected using a primary method , it uses statistical data collected by means of a questionnaire (Apuke, 2017). The purpose of quantitative research is to emphasize the collection of objective data in order to assess a social phenomenon. There are different types of quantitative research such as survey research, correlational research, descriptive research, experimental research, and causal-comparative research.

Descriptive research

Descriptive research is the research design in which data is collected in a qualitative manner and analyzed using quantitative procedures (Nassaji, 2015). Descriptive research refers to the scientific methodology in which observation of the sampled population is carried out in its natural surrounding. Descriptive research methodology intends to find out ‘what’ related to a phenomenon. In this method, data are collected qualitatively and analyzed through a quantitative method. Data is collected through methods like survey, interview, correlation study, observation study, or content analysis. Moreover, the observer does not intervene in this observation process or influence any of the variables of the study (Lambert and Lambert, 2012). 

Application of descriptive research

The use of descriptive research is mostly restricted to areas like education, nutrition, epidemiology . This is because it centers on the premise that certain problems can be resolved and practices can be improved by observation analysis, and description (Koh and Owen, 2000). Furthermore, this form of research methodology finds its most use in studies that are exclusively restricted to facts rather than hypothetical scenarios. Hence, a major feature of descriptive research is that it is restricted to examining facts and the researcher does not make any additional attempt to find out why the reality occurs in a particular form (Jong and Voordt, 2002).

For example, research to find out the demotivating factors in a Japanese classroom. The descriptive method is the most suitable method where the students can be observed in their natural classroom settings. Data can be collected from all or some of the students through a questionnaire-based survey method. Statistical analysis of the collected data will reveal demotivating factors such as attitude of teachers, nature of textbooks, school facilities, group attitude, etc.

Experimental research

Experimental research is a scientific methodological framework in which the researcher uses a set of variables for studying a given phenomenon. In this method, some of the variables are kept constant and others are altered in order to meet pre-determined research objectives (Mildner, 2019). This type of methodology is used in studies in which accuracy of statement is considered immensely important in the context of explaining cause and effect relationships of a particular phenomenon or issue.

Application of experimental research

Experimental research design is applicable in areas that are high in causal (or internal) validity, i.e. when a researcher wants to understand the cause-and-effect relationship between variables (Tanner, 2018). In experimental research, hypothesis is framed and tested. This type of research is considered to be the most thorough but suffers from lack of validity. This is because often the variables can be manipulated or controlled (Gravetter and Forzano, 2009).

For example, research to find out the effect of absenteeism on students’ academic performance. The researcher hypothesizes can be high absenteeism is directly related to poor academic performance. Experimental research is suitable in this case, as the researcher can survey 250 students of a university to examine the hypothesis.

The challenges of experimental research design include unnaturalness of the research situation because in this method calibrated situations are usually developed by the researchers for carrying a study. Therefore, it is often difficult to apply the study findings to a real-life situation.

Extensions of experimental research

Another type of research is quasi-experimental research, which is similar to pure experimental research, however, it is high in validity as there is no manipulation of variables, and respondents are not selected randomly. It is used mainly in medical studies. All the types of researches share some similarities as well as differences. A researcher must closely review the pros and cons of each type in order to choose the one which is most suitable for his study.

Descriptive research studies a particular population or sample that is representative of the larger population being studied. Furthermore, sampling methods can include convenience, stratified, or random sampling.

3. Data Collection Techniques

Descriptive research typically involves the collection of both qualitative and quantitative data through methods such as surveys, observational studies, case studies, or focus groups.

4. Data Analysis

Descriptive research data is analyzed to identify patterns, relationships, and trends within the data. Statistical techniques , such as frequency distributions and descriptive statistics, are commonly used to summarize and describe the data.

5. Focus on Description

Descriptive research is focused on describing and summarizing the characteristics of a particular population or phenomenon. It does not make causal inferences.

6. Non-Experimental

Descriptive research is non-experimental, meaning that the researcher does not manipulate variables or control conditions. The researcher simply observes and collects data on the population or phenomenon being studied.

When Can a Researcher Conduct Descriptive Research?

A researcher can conduct descriptive research in the following situations:

• To better understand a particular population or phenomenon
• To describe the relationships between variables
• To describe patterns and trends
• To validate sampling methods and determine the best approach for a study
• To compare data from multiple sources.

Types of Descriptive Research Design

1. survey research.

Surveys are a type of descriptive research that involves collecting data through self-administered or interviewer-administered questionnaires. Additionally, they can be administered in-person, by mail, or online, and can collect both qualitative and quantitative data.

2. Observational Research

Observational research involves observing and collecting data on a particular population or phenomenon without manipulating variables or controlling conditions. It can be conducted in naturalistic settings or controlled laboratory settings.

3. Case Study Research

Case study research is a type of descriptive research that focuses on a single individual, group, or event. It involves collecting detailed information on the subject through a variety of methods, including interviews, observations, and examination of documents.

4. Focus Group Research

Focus group research involves bringing together a small group of people to discuss a particular topic or product. Furthermore, the group is usually moderated by a researcher and the discussion is recorded for later analysis.

5. Ethnographic Research

Ethnographic research involves conducting detailed observations of a particular culture or community. It is often used to gain a deep understanding of the beliefs, behaviors, and practices of a particular group.

Advantages of Descriptive Research Design

1. provides a comprehensive understanding.

Descriptive research provides a comprehensive picture of the characteristics, behaviors, and attributes of a particular population or phenomenon, which can be useful in informing future research and policy decisions.

2. Non-invasive

Descriptive research is non-invasive and does not manipulate variables or control conditions, making it a suitable method for sensitive or ethical concerns.

3. Flexibility

Disadvantages of Descriptive Research Design

1. limited scope.

Descriptive research only provides a snapshot of the current situation and cannot establish cause-and-effect relationships.

2. Dependence on Existing Data

Descriptive research relies on existing data, which may not always be comprehensive or accurate.

3. Lack of Control

Researchers have no control over the variables in descriptive research, which can limit the conclusions that can be drawn.

The researcher’s own biases and preconceptions can influence the interpretation of the data.

5. Lack of Generalizability

Descriptive research findings may not be applicable to other populations or situations.

6. Lack of Depth

Descriptive research provides a surface-level understanding of a phenomenon, rather than a deep understanding.

7. Time-consuming

Descriptive research often requires a large amount of data collection and analysis, which can be time-consuming and resource-intensive.

7 Ways to Avoid Common Flaws While Designing Descriptive Research

1. Clearly define the research question

A clearly defined research question is the foundation of any research study, and it is important to ensure that the question is both specific and relevant to the topic being studied.

2. Choose the appropriate research design

Choosing the appropriate research design for a study is crucial to the success of the study. Moreover, researchers should choose a design that best fits the research question and the type of data needed to answer it.

3. Select a representative sample

Selecting a representative sample is important to ensure that the findings of the study are generalizable to the population being studied. Researchers should use a sampling method that provides a random and representative sample of the population.

4. Use valid and reliable data collection methods

Using valid and reliable data collection methods is important to ensure that the data collected is accurate and can be used to answer the research question. Researchers should choose methods that are appropriate for the study and that can be administered consistently and systematically.

5. Minimize bias

Bias can significantly impact the validity and reliability of research findings.  Furthermore, it is important to minimize bias in all aspects of the study, from the selection of participants to the analysis of data.

6. Ensure adequate sample size

An adequate sample size is important to ensure that the results of the study are statistically significant and can be generalized to the population being studied.

7. Use appropriate data analysis techniques

The appropriate data analysis technique depends on the type of data collected and the research question being asked. Researchers should choose techniques that are appropriate for the data and the question being asked.

Descriptive Research vs. Experimental Research

What's the difference.

Descriptive research and experimental research are two different approaches used in scientific studies. Descriptive research aims to describe and explain a phenomenon or behavior without manipulating any variables. It focuses on observing and documenting what is happening in a natural setting. On the other hand, experimental research involves manipulating variables to determine cause-and-effect relationships. It involves the use of controlled conditions and random assignment of participants to different groups. While descriptive research provides valuable insights into a particular topic, experimental research allows researchers to establish causal relationships and make predictions. Both approaches have their own strengths and limitations, and the choice between them depends on the research question and objectives.

Further Detail

Introduction.

Research is a fundamental aspect of the scientific method, allowing us to gain knowledge and understanding of various phenomena. Descriptive research and experimental research are two common approaches used in research studies. While both methods aim to gather information and provide insights, they differ in their objectives, designs, and data collection techniques. In this article, we will explore the attributes of descriptive research and experimental research, highlighting their similarities and differences.

Descriptive Research

Descriptive research is a type of research that aims to describe and explain the characteristics of a particular population or phenomenon. It focuses on observing and documenting existing conditions, behaviors, attitudes, or relationships without manipulating any variables. Descriptive research often involves surveys, interviews, observations, or existing data analysis.

One of the key attributes of descriptive research is its emphasis on providing a detailed and accurate portrayal of the subject under investigation. Researchers aim to collect data that represents the population or phenomenon as accurately as possible. This approach allows for the exploration of patterns, trends, and associations within the data.

Descriptive research is particularly useful in situations where the researcher wants to gain a better understanding of a specific population or phenomenon. For example, a researcher may conduct a descriptive study to examine the demographic characteristics and preferences of a target market for a new product. By collecting and analyzing data, the researcher can identify key trends and make informed decisions based on the findings.

Furthermore, descriptive research is often conducted in natural settings, allowing researchers to observe and document behaviors and interactions as they naturally occur. This approach enhances the external validity of the findings, making them more applicable to real-world situations.

However, one limitation of descriptive research is that it does not establish cause-and-effect relationships. While it can identify associations and correlations between variables, it cannot determine causality. This is where experimental research comes into play.

Experimental Research

Experimental research is a scientific method that involves manipulating one or more variables to observe the effect on another variable. It aims to establish cause-and-effect relationships by controlling and manipulating the independent variable(s) while measuring the dependent variable(s). Experimental research often involves the random assignment of participants to different groups or conditions.

One of the key attributes of experimental research is its ability to control and manipulate variables. By manipulating the independent variable(s) and controlling extraneous variables, researchers can isolate the effects of the independent variable(s) on the dependent variable(s). This control allows for the establishment of causal relationships, providing stronger evidence for the impact of certain variables.

Experimental research is particularly useful when researchers want to investigate the effects of specific interventions, treatments, or manipulations. For example, a researcher may conduct an experiment to determine the effectiveness of a new teaching method on student learning outcomes. By randomly assigning participants to different groups, such as a control group and an experimental group, the researcher can compare the outcomes and draw conclusions about the impact of the teaching method.

Furthermore, experimental research often involves rigorous data collection techniques, such as pre- and post-tests, to measure the changes in the dependent variable(s) before and after the manipulation. This allows researchers to quantify the effects and analyze the statistical significance of the results.

However, one limitation of experimental research is that it may not always be feasible or ethical to manipulate variables in certain situations. For example, it may not be possible to conduct experiments on certain social or environmental phenomena. In such cases, descriptive research can provide valuable insights without the need for manipulation.

Similarities

While descriptive research and experimental research differ in their objectives and designs, they also share some similarities. Both approaches involve systematic and scientific inquiry, aiming to gather data and provide insights into various phenomena. They both require careful planning, data collection, and analysis to ensure the validity and reliability of the findings.

Additionally, both descriptive research and experimental research can utilize quantitative or qualitative data collection methods. Surveys, questionnaires, interviews, and observations can be used in both approaches, depending on the research questions and objectives. The choice of data collection method often depends on the nature of the research and the availability of resources.

Moreover, both descriptive research and experimental research contribute to the advancement of knowledge in their respective fields. Descriptive research provides a foundation for understanding and describing phenomena, while experimental research allows for the establishment of cause-and-effect relationships. Together, these approaches complement each other and contribute to a comprehensive understanding of various phenomena.

Descriptive research and experimental research are two distinct approaches used in research studies. Descriptive research focuses on describing and explaining the characteristics of a population or phenomenon, while experimental research aims to establish cause-and-effect relationships by manipulating variables. Both approaches have their own strengths and limitations, and the choice of method depends on the research questions, objectives, and feasibility. By understanding the attributes of descriptive research and experimental research, researchers can select the most appropriate approach to address their research inquiries and contribute to the advancement of knowledge in their respective fields.
