%% Create Box Plots for Grouped Data % %% % Load the sample data. load carsmall %% % Create a box plot of the miles per gallon (|MPG|) measurements from the % sample data, grouped by the vehicles' country of origin (|Origin|). Add a % title and label the axes. boxplot(MPG,Origin) title('Miles per Gallon by Vehicle Origin') xlabel('Country of Origin') ylabel('Miles per Gallon (MPG)') %% % Each box visually represents the MPG data for cars from the specified % country. Italy's "box" appears as a single line because the sample data % contains only one observation for this group.
