encouraged to always report an effect size along with p-values. An effect size measure quantifies the strength of an effect, such as the distance between...

computing a combined effect size across all of the studies. As such, this statistical approach involves extracting effect sizes and variance measures...

size determination or estimation is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is...
