A web-based effect-size calculator for t-tests, ANOVA, multiple regression, and two-level multilevel models

 

Abstract

 

I present a web-based effect-size calculator for the computation of effect sizes with confidence intervals for t-tests, ANOVA, multiple regression, and multilevel models. The inputs for the calculator are values that can be obtained from commonplace statistical software, and complete datasets in certain situations.
