Participants (N=12) in a study were randomly assigned to one of two types of therapy – either talk therapy or drug therapy (n = 6 per condition). Mood scores were analyzed at two time points for all clients: 4 weeks and 12 weeks into the start of the therapy. Mood scores are presented in the table below, with higher scores indicating improved / more positive moods. Use the data to answer

Question
Participants (N=12) in a study were randomly assigned to one of two types of therapy – either talk therapy or drug therapy (n = 6 per condition). Mood scores were analyzed at two time points for all clients: 4 weeks and 12 weeks into the start of the therapy. Mood scores are presented in the table below, with higher scores indicating improved / more positive moods. Use the data to answer the questions in this set.
Expert Solution
Step 1

Between-subjects (BS): In this study design, different participants are assigned to different conditions.

Within-subjects (WS): In this study design, each participant is exposed to all of the conditions.

Hence, we can label

BS = Types of Therapy

WS = Number of weeks

In addition, BS has two (2) labels with talk or drug therapy. On the other hand, WS has two (2) labels with 4 weeks and 8 weeks.

Now, let's state our Hypothesis:

BS:

Null Hypotheses: There is no significant difference in their mood scores between talk and drug therapy.

Alternative Hypotheses: There is a significant difference in their mood scores between talk and drug therapy.
