Newsom: Stats Notes

Stats Notes contains over 25 "Web Lectures," notes, and handouts on introductory graduate-level statistics. Topics range from sampling distributions to logistic regression (scroll down to get started)

This material was designed for a long distance course I taught many years ago and better updated material covers much of the same topics in more depth (Univariate Quantitative Methods and Multivariate Quantitative Methods)

The course was designed for Masters students with health backgrounds, and so the examples are often medical or biological in nature.

The statistical notation follows the author of the text used for the class (Wayne W. Daniel, Biostatistics, 7^th Ed.) and is different from what I currently use in my courses or in other handouts on this site. It is probably healthy to be exposed to another notation system, even though it may be confusing if you have to use two systems at the same time.

There may be a few typos or other minor errors (what do you expect for free?).
