Description
Overview: This lesson centers around the marginal value theorem (MVT, Charnov 1976), which describes how animals should forage in patches. The students will complete a lesson in R to practice using data they will collect directly as they ‘forage’ in an in-class lab. Specifically, they will practice creating vectors and tables of data to use in plotting and creating an ANOVA to compare high-, medium-, and low-density patches by their associated giving-up time (GUT) data. Students are then expected to repeat the coding steps they learned in R with example data to later test a hypothesis of their own.

Notes
This version removes dependencies by reordering the statistics and plotting lessons. We have also added information on how/why to conduct a t-test to contrast with the ANOVA suggested as part of the lesson.
