Stats Notes 
Stats Notes contains over 25 "Web
Lectures," notes, and handouts on introductory graduatelevel
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 (Data Analysis I
and Data Analysis II) 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?).
