1.The article with this assignment describes a study that examined using exercise as a treatment for depression.Read it and answer the following questions. (You may skip over technical results where ANCOVA and are mentioned. Refer to Chapters 10-11 and your notes when answering these questions.)

a)Who are the subjects in this study (experiment)?Be specific in describing the subjects and how many subjects were included.

b)A special type of random sampling design was used in this study to assign treatments. What was it?

c)What were the three treatments (combinations of independent variables) used for the study (experiment)?

d)In general, we can say that the dependent variables were the levels of depression measured several times throughout the 16-week study. How did the researchers measure the subjects' levels of depression?

e)How did the researchers attempt to ensure that confounding and lurking variables were eliminated from the experiment? Think about considerations that were made before the actual experiment started and those used in the design of the experiment.

f)Many of the statistical methods mentioned in the article are beyond the scope of our course (ANCOVA, multivariate analysis, etc.).What were some statistical methods mentioned that we have talked about? (These may be any specific measurements, graphs, methods, etc. that we have discussed this semester.)Please list at least three.

g)Does the study support that exercise is an effective treatment for depression in elderly adults? Why or why not?

I appreciate it a lot if anyone can help me this assignment!
