You carried out a study where you tested the effectiveness of a new therapy technique at reducing anxiety.You identified a group of high-anxiety individuals,and you measured their anxiety before therapy,immediately after therapy,and at two follow-up sessions 1 month and 2 months after the therapy is concluded.High scores on the anxiety measure are scaled to reflect relatively higher levels of anxiety.Here is the hypothetical data from SPSS output.
