Ok, I got the anonymous data downloaded, and I made nice tables, labeled the headers, etc. Now I have data to work with. However, I need to split the data into class labels, and what they are asking me to do is very arbitrary. I know one thing, I need to split the data into + and -. And then after that I can run the t-test and the chi-square test. Any help is greatly appreciated. No, I don’t expect anyone to give me the answers, just some pointers.
