An analysis is reproducible when independent individuals are able to perform the same analysis on the same data. Sharing meta-analytic data does not just facilitate future meta-analyses but also makes it possible for researchers to easily reproduce the published analyses.
Are meta-analysis reproducible?
Like other kinds of research, meta-analyses must be reproducible to be compliant with the principles of the scientific method. Furthermore, reproducible meta-analyses can be easily updated with new data and reanalysed applying new and more refined analysis techniques.
What is meta-analysis in psychology?
n. a quantitative technique for synthesizing the results of multiple studies of a phenomenon into a single result by combining the effect size estimates from each study into a single estimate of the combined effect size or into a distribution of effect sizes.
What is an example of meta-analysis in psychology?
There are many meta-analyses in psychology and medicine, areas where studies find often conflicting results. For example, some experiments might find that a particular drug decreases the risk of heart attack, while other experiments might find the drug doesn’t have any particular effect.
Why is meta-analysis used in psychological research?
Meta-Analysis “Increases” Sample Size
When individual research projects don’t study a significant number of subjects, it can be difficult to draw reliable and valid conclusions. Meta-studies help overcome the issue of small sample sizes because they review multiple studies across the same subject area.
What is meta analytic approach?
Meta-analysis refers to the statistical analysis of the data from independent primary studies focused on the same question, which aims to generate a quantitative estimate of the studied phenomenon, for example, the effectiveness of the intervention (Gopalakrishnan and Ganeshkumar, 2013).
What is the main purpose of a meta-analysis?
Meta-analyses are conducted to assess the strength of evidence present on a disease and treatment. One aim is to determine whether an effect exists; another aim is to determine whether the effect is positive or negative and, ideally, to obtain a single summary estimate of the effect.
What is the purpose of a meta-analysis?
Meta-analysis would be used for the following purposes: To establish statistical significance with studies that have conflicting results. To develop a more correct estimate of effect magnitude. To provide a more complex analysis of harms, safety data, and benefits.
What is meta-analysis in counseling?
A meta-analysis is a quantitative research procedure used to synthesize the results of many similar empirical studies on a topic of interest.
