Solution

A social worker tracked the depression levels of clients being treated with cognitive-behavioral therapy for depression. For each client, depression was assessed at weeks 1 to 20 of therapy. She calculated a mean for all of her clients at week 1, week 2, and so on, all the way through to 20.

what are the independent and dependent variables?

independent variable = cognitive-behavioral therapy

and dependent variable= depression score

The independent variable is nominal (treatment given)

dependent variable is scale ( since mean is calculated)

which graph or graphs would be most appropriate to depict the data? why?

Line graph with week in the x axis and mean score in the y axis. This graph will show data over time and easy to see the mean score increases or decreases over time.
