hypothesis resolution, and implications of your findings.

The staff at a mental health clinic wants to determine if their current form of short-term therapy substantially reduces depression. Prior to treatment, each patient will be asked to complete the Acme Depression Inventory (ADI), which renders a score from 0 to 75 (0 = low depression, 75 = high depression). Patients will also be asked to complete the same instrument at the conclusion of their final appointment.

Data set: Ch 07 – Exercise 04A.sav Codebook Variable: ID Definition: Participant’s initials Type: Alphanumeric Variable: pretest Definition: ADI score before treatment Type: Continuous (0–75) Variable: posttest Definition: ADI score after treatment Type: Continuous (0–75)

1. Write the hypotheses.

2. Run the criteria of the pretest checklist (normality for posttest − pretest) and discuss your findings.

3. Run the paired t test and document your findings (means and significance [p value], hypothesis resolution).

4. Write an abstract up to 200 words detailing a summary of the study, the paired t test results, hypothesis resolution, and implications of your findings.
