This is a course for first-year graduate students in the social sciences. It is the first part of a two-part sequence (SOC 510- 610), which forms the core statistics sequence in the department of sociology. The role of SOC 510 in this sequence is: a) development of the background for probability distributions, estimators of summary statistics of those distributions, and inferential procedures from sample-based estimators; b) introduction of the general linear model, which forms the basis of the analysis of variance, simple and multiple regression; and c) experience in the use of a statistical computing package for the analysis of quantitative data.
