I love stats because I am fascinated by its power in bringing order out of chaos, to elucidate patterns and to test hypotheses for gaining new knowledge. This is a site for you who want to learn statistical theory for conducting and understanding the background of statistical analyses. The site is thus best suited for students and researchers with an interest of learning statistics. I will also show you how to do it in the open source statistical software R. Forget about expensive statistical tools such as SPSS or SAS.
