Teaching guide

What students learn

Compare distributions of continuous numerical data with displays such as boxplots, discussing centre, spread, shape and outliers.

How to teach it

Summarise continuous numerical data with box plots (five-number summary), then compare centre, spread, shape and outliers across groups in context.

Worked example
Data set (already sorted): 4, 7, 9, 10, 21, 22, 31, 50. Find the median.
Answer: 15.5
Why: five-number summary: min 4, Q1 8, median 15.5, Q3 26.5, max 50

Generated and checked in code, so it is correct.

Watch out for

Misreading the box (the middle line is the median, not the mean) and forgetting to check for outliers.
