Here are boxplots of SSHA scores, by gender. Exploring the relationship between a
categorical explanatory variable and a quantitative response variable amounts to
comparing the distributions of the quantitative response for each category of the
OM
explanatory variable. In particular, we look at how the distribution of the response
variable differs between the values of the explanatory variable. With this in mind,
answer the following series of questions to summarize the results and interpret them.
