This document consists of unrevised lecture notes for the first half of a 20-week in-house graduate course at Rand Corporation. The chapter headings are: (1) Histograms and descriptive statistics; (2) Measures of dispersion, distance and goodness of fit; (3) Using JOSS for data analysis; (4) Binomial distribution and normal approximation; (5) Estimation and hypothesis testing; (6) Correlation and regression; (7) Multiple correlation and multiple regression; (8) Testing in correlation and regression; and (9) Transformations of data, stepwise regression, partial correlation. The level is pre-calculus, and the computer is used to teach techniques. The participants use a specially designed package of statistical programs (JOSS), available through a computer terminal, and the notes frequently display computer input and output. Included in the notes are homework assignments, a final test paper, and standard statistical tables. (MM)
