6.2.B The mean, median, mode and range for a discrete data question 1
[Maximum number: 1]
Here are the numbers of aces that Rutger served in each of 11 tennis matches.
1, 1, 2, 4, 6, 8, 8, 9, 11, 12, 15
Kim also plays in 11 tennis matches.
For Kim, the median number of aces is 11 and the interquartile range of the numbers of aces is 5.
State, giving a reason, whether Rutger or Kim
served more aces on average,
Final answer:
Kim, because she has a higher median.
B1 oe, follow through their median if a value is given.
Accept examples:
- Kim as she has a higher median.
- Kim because her median is 11 whereas Rutger's is 8.
- Kim's median is 3 more than Rutger's.
- Kim as Rutger's median is 3 less.
Do not accept examples:
- Kim's median is 11 and Rutger's is 8, without comparison.
- Kim as she has a higher median and a lower IQR.
