In this lesson, students will learn how to do a one-way analysis of variance (ANOVA) using a dataset that relates water flea (Daphnia spp.) growth rates to the presence and identity of three different parasites in a well-replicated manipulative experiment. Students will follow a specific workflow introduced in Chapter 5 of Beckerman et al. (2017): Getting started with R: an introduction for biologists, 2nd edition. Proceeding step-by-step in a directed tutorial, students will accomplish a core data visualization and analysis process they are likely to encounter frequently in their future careers. As the tutorial follows the organization of a specific book chapter, students will be able to read in more detail about any of the steps where they might get confused. They will then have a chance to analyze a similar dataset on their own in a follow-up homework assignment using an R Markdown document.
