I'd like to get some real practice with hypothesis testing that is above what's in textbooks (plug and chug, usually). I was hoping someone could suggest some good data sets and problems to work on. Problems that I could show others that I've worked on. Along those lines, I'd very much appreciate any top notch references on the topic.
You are supposed to form your hypotheses before seeing any of the actual data. These hypotheses come from some sort of conceptual frame work. Your best bet may be to form a hypothesis on a topic of interest to you and then try to find a data set to test that hypothesis.
