  1. Meta-analysis

    Meta-analysis is a method of synthesis of quantitative data from multiple independent studies addressing a common research question. An important part of this method involves computing a combined effect size across all of the studies. As such, this statistical approach involves extracting effect sizes and variance measures from various studies. By combining these effect sizes the statistical ...

  2. Meta-Analysis

    The final step of literature meta-analysis is to report the results. They should be comprehensive and precise for the reader's understanding. Meta-Analysis Vs Systematic Review. A systematic review is a comprehensive analysis of existing research, whereas a meta-analysis is a statistical analysis or combination of results from two separate ...

  3. Doing a Meta-Analysis: A Practical, Step-by-Step Guide

    Meta-analysis is a statistical procedure used to combine and synthesize findings from multiple independent studies to estimate the average effect size for a particular research question. Meta-analysis goes beyond traditional narrative reviews by using statistical methods to integrate the results of several studies, leading to a more objective ...

  4. How to conduct a meta-analysis in eight steps: a practical guide

    2.1 Step 1: defining the research question. The first step in conducting a meta-analysis, as with any other empirical study, is the definition of the research question. Most importantly, the research question determines the realm of constructs to be considered or the type of interventions whose effects shall be analyzed.

  5. What is Meta-Analysis? Definition, Research & Examples

    Meta-analysis is a quantitative research method that involves the systematic synthesis and statistical analysis of data from multiple individual studies on a particular topic or research question. It aims to provide a comprehensive and robust summary of existing evidence by pooling the results of these studies, often leading to more precise and ...

  6. What is meta-analysis?

    What is meta-analysis? Meta-analysis is a research process used to systematically synthesise or merge the findings of single, independent studies, using statistical methods to calculate an overall or 'absolute' effect.2 Meta-analysis does not simply pool data from smaller studies to achieve a larger sample size. Analysts use well recognised, systematic methods to account for differences in ...

  7. Meta-analysis

    Meta-analysis is an objective examination of published data from many studies of the same research topic identified through a literature search. Through the use of rigorous statistical methods, it ...

  8. Study Design 101: Meta-Analysis

    1. A Meta-Analysis pools together the sample populations from different studies, such as Randomized Controlled Trials, into one statistical analysis and treats them as one large sample population with one conclusion. a) True b) False. 2. One potential design pitfall of Meta-Analyses that is important to pay attention to is:

  9. Meta-analysis

    Meta-analysis, in statistics, approach to synthesizing the results of separate but related studies. In general, meta-analysis involves the systematic identification, evaluation, statistical synthesis, and interpretation of results from multiple studies. It is useful particularly when studies on the

  10. The Power and Pitfalls of Meta-Analysis in Research Synthesis

    Meta-analysis is a cornerstone of evidence-based research, offering a powerful means of aggregating data, resolving discrepancies, and uncovering insights. However, its potential can be undermined by pitfalls such as publication bias, the inclusion of low-quality studies, and the influence of small sample sizes.
