16 Here is some information about the lengths, in cm, of leaves.
- Shortest length \(= 2.4\)
- Longest length \(= 9\)
- Upper quartile \(= 7\)
- Median length \(= 6\)
- Interquartile range \(= 3\)
Draw a box plot to show this information. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Fully correct box plot with shortest at 2.4 cm LQ at 4 cm median at 6 cm UQ at 7 cm longest at 9 cm | B3 | mark intention B2 box plot with four correct plots and one incorrect/omitted plot or box plot with five correct plots and at most one extra plot B1 at least three correct plots |
Additional guidance
A box plot must be a rectangle with ‘whiskers’
Accept ‘whiskers’ ending in points rather than vertical lines
For B2 condone the median given as a point in the rectangle
