Creating Box Plots
Step 1: Find the Five-Number Summary
- Arrange data in order: Sort from smallest to largest
- Find the median (Q2): Middle value of the dataset
- Find Q1: Median of the lower half
- Find Q3: Median of the upper half
- Identify minimum and maximum: Smallest and largest values
Example: Finding Five-Number Summary
Step-by-step:
• n = 11 (odd number)
• Median (Q2): 6th value = 28
• Lower half: 12, 15, 18, 22, 25 → Q1 = 18
• Upper half: 30, 35, 38, 42, 45 → Q3 = 38
• Minimum: 12
• Maximum: 45
Five-number summary: 12, 18, 28, 38, 45

Practice Questions for Box Plots
On a box plot, what does the box (the rectangle) represent?
Two athletics clubs record the 100m sprint times (in seconds) for their members. The five-number summaries are shown below. Club A: Min = 11.2, Q1 = 12.4, Median = 13.1, Q3 = 14.2, Max = 16.5 Club B: Min = 12.0, Q1 = 13.5, Median = 14.8, Q3 = 16.1, Max = 17.3 Compare the distributions of sprint times for the two clubs. You must use the data to support your answer. (3 marks)
