- M1: (6 - 2)² + (8 - 3)²
- M1: √41 = 6.4031ldots
- A1: 6.4
Answer: 6.4[3 marks] - 2
Question 2. Group P: median 61, interquartile range 14. Group Q: median 55, interquartile range 14. Compare the two groups.
Comparing Data Using Box Plots▶ Show worked answerHide worked answer
- B1: P higher on average (median 61 > 55)
- B1: same consistency (IQR 14 = 14)
Answer: P has the higher average (61 > 55); the spread is the same (14 = 14)[2 marks] - 3
