Ma'am, you have taken two experimental group and control group. But in every research there is no experiment and control group, then how can we calculate effect size

[@rupambanerjee2066]

If a study has no control group that means it is a quasi experimental design. If it is an independent group design then Effect size cannot be calculated.
