Objectives and pitfalls of statistical studies. Structure of data sets, histograms, means, and standard deviations. Correlation and regression. Probability, binomial and normal. Interpretation of estimates, confidence intervals, and significance tests. (Students may receive credit for only one of STAT 220, STAT 221, STAT 311, and ECON 311.) Offered: AWSpS.
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.

General method of instruction
Activity-based, Example-oriented, Interactive.
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.
