Content

What is this course about?

This is an introductory statistics course intended for undergraduate students. Topics include exploratory data analysis (graphs and simple summary statistics), inference using hypothesis tests and confidence intervals, simple linear regression, one-way ANOVA, and chi-squared tests for two- way tables. Emphasis will be placed on being able to use these tools with real data. Students are expected to be comfortable with computers as we will be using R on a regular basis.

“All models are wrong, but some are useful.” – George E. P. Box
