An introduction to data analysis, with coverage of both descriptive and inferential statistics, and an introduction to probability. Class discussions focus on the use of sample, sampling, and population distributions as they are employed in hypothesis testing. Inferential tests include t-tests, ANOVAs, chi square, regression, and nonparametric tests. Note: This course may be used to satisfy the statistics requirement for economics and environmental studies majors, and it counts as a basic science support course for biology majors.
