This lesson introduces students to the three-pronged approach for checking normality. During the lesson, students visualize the distribution of a continuous numerical variable in a biological data set using histograms and normal quantile plots, and perform a goodness-of-fit test. By comparing their outputs to a known normally distributed variable, students are able to correctly interpret the results of this three-pronged approach when working with data that deviates from a normal distribution.
