  1. Matched Pairs Design: Definition + Examples

    A matched pairs design is an experimental design that is used when an experiment only has two treatment conditions. The subjects in the experiment are grouped together into pairs based on some variable they "match" on, such as age or gender. Then, within each pair, subjects are randomly assigned to different treatments.

  2. Matched Pairs Design: Uses & Examples

    A matched pairs design is an experimental design where researchers match pairs of participants by relevant characteristics. Then the researchers randomly assign one person from each pair to the treatment group and the other to the control group. This type of experiment is also known as a matching pairs design.

  3. Experimental Design: Types, Examples & Methods

    Matched pairs: Each condition uses different participants, but they are matched in terms of important characteristics, e.g., gender, age, intelligence, etc. Learning Check. Read about each of the experiments below. For each experiment, identify (1) which experimental design was used; and (2) why the researcher might have used that design.

  4. Matched Pairs Design: An Introduction

    A matched pairs design is better than a simple randomized trial when we want to enforce a balance between important participant characteristics that may influence the outcome. For example, a lot of outcomes are gender and age specific. Therefore, matching individuals on these 2 variables will help improve the validity of the study by reducing bias.

  7. 8.1 Inference for Two Dependent Samples (Matched Pairs)

    Two samples that are dependent typically come from a matched pairs experimental design. The parameter tested using matched pairs is the population mean difference. When using inference techniques for matched or paired samples, the following characteristics should be present: Simple random sampling is used. Sample sizes are often small.

  9. Matched-Pairs Design

    Matched-Pairs Design is a statistical method used in experiments where participants are paired based on certain characteristics, ensuring that each pair is similar in key aspects. This design helps to control for confounding variables and increases the sensitivity of the experiment, allowing for a clearer comparison between two treatments or conditions.

  10. Matched Pairs Design

    Matched pairs design is a research method used in experimental and quasi-experimental research to control for extraneous variables and reduce the influence of individual differences among participants. In this design, participants are paired based on similar characteristics or traits that are relevant to the….

    A Level Psychology Topic Quiz - Research Methods. Quizzes & Activities. Matched pairs design is an experimental design where pairs of participants are matched in terms of key variables, such as age and IQ. One member of each pair is then placed into the experimental group and the other member into the control group.

  12. Matched-Pairs Design

    Matched-pairs design is a randomized block design experiment. Matched-Pairs Design Example When designing an experiment, one would first make sure that the matched-pair experimental design would ...

  13. Matched Pairs Design vs Randomized Block Design

    In a matched pairs design, treatment options are randomly assigned to pairs of similar participants, whereas in a randomized block design, treatment options are randomly assigned to groups of similar participants. The objective of both is to balance baseline confounding variables by distributing them evenly between the treatment and the control ...

  14. Hypothesis Testing: Matched Pairs

    The Test Statistic for a Test of Matched Pairs (2 Means from Dependent Samples): t = ¯x − 0 s √n t = x ¯ − 0 s n. n n is the sample size, or the number of pairs of data. df = n −1 d f = n − 1 is the degrees of freedom. μd μ d is the mean value of the differences for the population of all matched pairs of data.

  15. Matched Pairs Design: Definition

    A matched pairs design is an experimental design that is used when an experiment only has two treatment conditions. The subjects in the experiment are grouped together into pairs based on some variable they "match" on, such as age or gender. Then, within each pair, subjects are randomly assigned to different treatments.

  17. Experimental Design

    Matched Pairs Design. A matched pairs design is a special case of the randomized block design. It is used when the experiment has only two treatment conditions; and participants can be grouped into pairs, based on one or more blocking variables. Then, within each pair, participants are randomly assigned to different treatments.

  18. 10.4 Matched or Paired Samples

    In a hypothesis test for matched or paired samples, subjects are matched in pairs and differences are calculated. The differences are the data. The population mean for the differences, μ d , is then tested using a Student's-t test for a single population mean with n - 1 degrees of freedom, where n is the number of differences.

  19. What is Pair Matching in Experimental Groups?

    A blog article by Ashlie Reker Ph.D. Pair Matching is a method of splitting study subjects into experimental groups in a way that limits the possibility of independent variables skewing the study results. To run a scientific study using Pair Matching, study subjects are placed into experimental groups based on specific blocking variables.
