a contingency table
This is not quite right. Remember that side-by-side boxplots are the appropriate display for comparing
several groups of
data (that is, for the relationship between a categorical explanatory
variable and a
response variable). But in this exercise, both variables are categorical. Try to
remember the appropriate display for this comparison. (E) is the correct answer.
Good job! A scatterplot is the appropriate display for comparing two quantitative variables (in other
words, to display the relationship between a quantitative explanatory variable, in this case "annual
income," and a quantitative response variable, in this case "amount spent on entertainment").
