Question

Quizplus · Accepted Answer

A large effect size indicates that the difference between groups is not only statistically significant but also practically meaningful or important. It suggests that the independent variable has a strong influence on the dependent variable. Covariation between the variables may or may not be present, and mundane realism is not related to effect size.
