Class description

Stat 220 is an introduction to statistical reasoning. This course focuses primarily on the "what" and "why", rather than the "how". Students will gain an understanding of the rationale behind many statistical methods, as well as an appreciation of the use and misuse of statistics. This course encourages and requires critical thinking.

Student learning goals

Students will be able to appreciate the role of statistics in modern life.

They will become familiar with the various stages of a statistical investigation, beginning with the design of a study to the analysis and presentation of results.

They will understand important concepts such as randomness, bias, sampling, confidence and significance.

Students will learn to critically read and evaluate published results.

General method of instruction

Activity-based, Example-oriented, Interactive.

Recommended preparation

I recommend that students brush up on their basic algebra skills before the course begins. In addition, fluency in the English language is a must as there will be a fair amount of writing and reading in this course.
