I'm talking about where can i find out about t-tests, chi squares, and other statistical data analyses. As in, I've done clinical research before and performed the basic excel tests like mean, standard deviation etc. but my mentor performed the higher level tests. I was second author on those pubs, but if I ever want to strike out on my own, I need to know how to do these on my own. So I want to know where I can find out about how to conduct these on my own for my own research paper.
