Core Mathematics - Parallel boxplots

Parallel boxplots

Multiple boxplot solution

Parallel boxplots are used to display the relationship between a_
numerical _variable and a _categorical_ variable with_two or more _values.
This is done so we can compare sets of data and draw conclusions about the
categories we are looking at.

Display the data in the previous example as two parallel boxplots.

Comments: Scores from class A have a much greater spread than those from
class B, however class B has a slightly higher median score than class A.
Both have slight negative skews.
