Question 2. Set P has median 40 and interquartile range 12. Set Q has median 46 and interquartile range 20. Write down which set has the higher typical value and which has the more consistent values.
Comparing Data Using Box Plots▶ Show worked answerHide worked answer
- B1: Q has the higher median
- B1: P has the smaller interquartile range, so is more consistent
Answer: Q has the higher typical value; P is more consistent.[2 marks] - 3
