Abstract

A very(sic) design in quantitative research involves the random allocation of a sample of N individuals to two different groups. The groups are exposed to different treatments, and the research question examines whether there is any difference between the two groups on some criterion variable. Classically, this question is addressed using Student’s t test for independent groups (or the equivalent one-way between-subjects analysis of variance).
