Document Summary
Day 1: intro to the course [jan 09] Statistics: the study of the collection, organization, analysis, interpretation, and presentation of data. A tool that scientists use to make decisions in the presence of uncertainty. Goal: to understand how to use statistics to understand, and make decisions about, biological data. What types of data can statistics help us understand? types of evidence: A short story or an example of an interesting event single/very few observations that are dramatic, so we attach a high level of importance to them. Why is anecdotal evidence not compelling? the selection of subjects is biased. Often observations made on one or a small number of subjects. Other factors that can affect the outcome are not measured or controlled. Only the most compelling anecdotes get told ( cherry picking") A researcher collects data from a sample of subjects, but does not manipulate conditions. Way better than anecdote, but correlation is not causation.
