Where can I find statistical sample data to perform ANOVA or REGRESSION yses on it?

Generate your own. Just open excel and create variables (2 factor, 3 factor, etc.). You could compare the effects of IQ and memory strategy (e.g., whether they read a list of words, created a rhyme, or nothing). Then you could list the IQs (100, 95, 90, 105, 99, 101, 110, 115). You'd want your data to be normally distributed. Check your spread of IQs, get the value for the 75th percentile and 25th. Then code your IQs as being high or low. Voila, you can run either regression or a 2x3 ANOVA.
