The students will practice identifying the appropriate basic statistical tests when given a scenario and learn how to run and interpret those statistical tests in R.


This lesson centers around introducing 4 fundamental statistical tests used in biology: correlations, t-tests, ANOVAs, and X2 (chi-square) tests. Students will first work through a worksheet to identify when each test should be conducted and what the appropriate research hypothesis would be for each experiment. Students then turn to swirl to dig into statistical hypotheses in the context of these scenarios to run and interpret statistical analyses in R.

Learning objectives:

  1. Identify experimental variables and the appropriate basic statistical test for a given scenario
  1. Practice coding elements necessary to run a statistical test in R
  1. Interpret the output of a statistical test relative to a research question/hypothesis



Correction of a minor typo in the guiding text of the lesson.
