It is false that for visualizing the relationship between a numerical and a categorical variable, a mosaic
plot is useful. This is because the best plot to use for this kind of
relationship is the side by side box plot.
Comparing the
distribution of a numerical variable across the levels of a categorical
variable is something we usually consider in this type of relationship.
The levels of one categorical variable by means of a quantitative
variable is best compared by using the visual display called the side by side

another on a single scale, the side by side box plot is constructed.</span>
Car A travels 180miles in 7 hours
Car A travels 25.7 miles an hour because 180/7 = 25.7
Car B travels 350 miles in 4 hours
Car B travels 87.5 miles an hour because 350/4= 87.5
Car C travels 584 miles in 15 hours
Car C travels 38.9 miles an hour because 584/9 = 38.9
Car B has the fastest average speed
