1) Your lab should be on the data on Depression (Sheet 1 data). The other data is for your reference and to help facilitate completing the lab.
2) You can get an additional extra credit point if you test if depression before treatment was different for the two groups. You will only get credit if the answer to this question is both in your results (APA format) and then discussed in your discussion.
You now find (in Lab 2 materials) a file called “Participant Information” that describes who was recruited for the RCT, what the exclusion and inclusion criteria was, and what protocol they went through. This will facilitate you accurately having information in your methods section of Lab 2.
