Abstract

Statistical significance tests have a tendency to yield small p-values (indicating significance) as the size of the data sets increase. The effect size is independent of sample size and is a measure of practical significance. It can be understood as a large enough effect to be important in practice and is described for differences in means as well as for the relationship in two-way frequency tables and also for a multiple regression fit.
