Communication Studies (CMNS) 308

Overview

Many people working in journalism, public relations and other communications fields need to be able to understand how statistics are used in order to present information and frame arguments. This course is designed for those who want to become critical consumers of statistical evidence. It emphasizes a conceptual rather than a computational approach to learning statistics. Using examples taken from popular media, the course explains how people use and abuse statistics for purposes of persuasion and influence.
