Overview: This course centers on learning biometry through weekly practice and experimentation. The goal is to learn the rationale and mathemetics behind upper level biometrical methods. We will construct spreadsheets and analyze a common dataset each week. Students pick topics and serve as moderator for two or three discussions. Students end up with a portfolio of spreadsheets for most major methods in biometry.
