Description

This course teaches the fundamentals of statistics, that is, the ability to describe data samples and draw inferences about the populations from which they were drawn. It should also sharpen individual intuition about how to read data, interpret data, and judge others' claims about data.

Specifically, at the end of this course students should be able to:
• characterize population data intuitively for themselves and others;
• draw conclusions and inferences from population data;
• check assumptions of others' claims and debug their putative "facts";
• look for correlations while controlling for confounding effects

Prerequisites: none

Reading: We will be using two textbooks:

• Introductory Statistics for the Behavioral Sciences (5th Edition) by Welkowitz, Ewen, and Cohen (the publisher is just coming out with the 6th edition, but we'll be sticking with the 5th).
• Introductory Statistics with R (Paperback) by Peter Dalgaard

Both books will be available at Ulrich's.
