The freely available statistics program XLispStat, written by Luke Tierney at the University of Minnesota, can be used both as somewhat of a tutorial for the material here as well as to do basic statistical computations. The first 106 pages of Statistics and Econometric Using XLispStat (stemlisp.ps -- 2500k) PDF version (stemlisp.pdf -- 1128k) are well worth working through in conjunction with the material below if one wants to achieve a solid basic understanding of statistical concepts.
This material should be useful for people who have studied statistics some time ago and need a review of what they are supposed to have learned. Indeed, one could learn statistics from scratch from this material alone, although those trying to do so may find the presentation somewhat compact, requiring slow and careful reading and thought as one goes along.
I would especially like to thank my colleague Gordon Anderson who has answered so many of my questions and clarified so many issues for me in basic statistics that he deserves the status of mentor.
You can download the entire document in one PDF file (ecstats.pdf -- 1054k). Alternatively, you can download ir chapter by chapter below. The first chapter contains the table of contents and the index. After each chapter you can download a test covering the material it contains. A detailed answer for each test is also provided in a separate file along with instructions on how to grade yourself on your performance. Download the answers AFTER you have completed the corresponding test.
