Below are the lecture notes from my introductory statistics course at Pellissippi State.
Topics covered include descriptive statistics, the normal distribution, confidence intervals, hypothesis testing, linear correlation and regression, and inference for categorical variables (tests of independence and goodness-of-fit tests).
Note: in this class, we use a software package called StatDisk, which is a free download from our textbook publisher. For the most part, any statistical program (Stata, SPSS, R, etc) can be substituted in these notes.
