Differences in Earnings Across Sex and Educational Attainment: Comparing Box Plots

Activity Description

Differences in Earnings for Men and Women

Students will interpret box plots that represent the national median earnings of men and women aged 25 and older whose highest levels of educational attainment are either a high school diploma (or equivalent) or a bachelor’s degree. Students will use the box plots to identify each data set’s median, maximum, minimum, first quartile, third quartile, range, interquartile range, and outliers. They will also compare the box plots to draw conclusions about differences in earnings between the sexes and between levels of educational attainment.
