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.

Unit 1: Why Study Statistics?
The history of statistics, the importance of studying statistics, and the scope, structure, and mechanics of the course.

Introduction to experimental designs and their implications for making causal statements; recognizing elements of bias in designs.
Unit 4: Measurement
A focus on the reliability and validity of the numbers generated in research; making informed judgements about reported conclusions based on numbers.

Unit 6: Understanding Relationships
Relationships between measures, or variables; understanding the results of multiple-variable research and the validity of related conclusions.
Unit 7: Probability: The Language of Chance
The language of probability, or the degree of likelihood of the occurrence of an event; the importance of probability for statistical tests of significance.
