This course provides a theoretical background and practical experience to statistics for psychology and other behavioral sciences. Statistics are the tools we use to summarize and describe the world around us and to explore the causal processes at work. Understanding statistics and how they are used and misused is vital to assimilating information as an informed citizen, as well as pursuing a career in the behavioral sciences or similar fields. In this course, we cover topics including principles of measurement, measures of central tendency and variability, probability and distributions, correlation and regression, hypothesis testing, t-tests, analysis of variance, and chi-square tests. Students may count one of the following courses toward a degree, but not all four: STAT E-100, STAT E-101, STAT E-102, or STAT E-104. The recorded lectures are from the Harvard Faculty of Arts and Sciences course Psychology 1900.
