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.

As an initial observation (that is,recognizing that significance tests have not been interpreted yet),what does the pattern of the means across the four measurement times suggest about the effectiveness of the new therapy technique?
A)The technique does seem to be reducing anxiety over time.
B)The technique is actually increasing anxiety over time.
C)The technique does not appear to be having any influence on anxiety over time.

The pattern of means across the four measurement times suggests that the therapy technique is reducing anxiety over time. The mean anxiety scores decrease from pre-therapy to post-therapy assessment and continue to decrease further at the follow-up sessions after 1 month and 2 months. This suggests that the therapy is effective in reducing anxiety in high-anxiety individuals.
