Course description

Good reasoning depends on information that can answer the question being asked. This course explains how to judge evidence without expecting any source or study to be perfect. Begin with the origin and relevance of a claim. Then examine what numbers measure, who is included in a sample, and whether a comparison is fair. The final units distinguish association from causation and explain how tests can help separate competing explanations. The emphasis is on understanding the method and the limits of its result.
