Understand that a meta-analysis is a statistical technique used in psychology to combine the results of multiple studies addressing the same question.
Recognize that by aggregating data from various studies, meta-analyses increase the overall sample size, which enhances the reliability and generalizability of the findings.
Note that meta-analyses focus on quantitative data, specifically effect sizes, to provide a more precise estimate of the true effect across studies.
Understand that meta-analyses do not eliminate the need for peer review; rather, they are themselves subject to rigorous peer evaluation to ensure validity.
Realize that meta-analyses are primarily used to test hypotheses by synthesizing existing research findings, rather than just generating new hypotheses.
