## Course Objectives

- Data production and analysis
- Probability basics, distributions
- Sampling, estimation with confidence intervals, hypothesis testing, t-test
- Correlation and regression
- Cross-tabulations and chi-square
- Students learn to use a statistical package such as SPSS, R, or Minitab.

## Problem Sets

### Use of Problem Sets

The problem sets were assembled to allow for personalization by individual faculty. The topics covered are fairly standard in a beginning statistics course, but faculty can rearrange the topics and delete any sections they do not wish to cover, or wish to assess by other means. The names of the problem sets are meant to be descriptive and the learning objectives will help you evaluate if the set should be included or not.

### Download the problem sets

A copy of the course can be found at Elementary Statistics at the MAA website

The course can be downloaded here Elementary Statistics File (.tgz format).

This file can now be directly uploaded into your own course:
