To find the interquartile range of a data set, we first need to calculate the first quartile (Q1) and the third quartile (Q3).
1. Arrange the data set in ascending order:
4, 5, 7, 9, 10, 14, 16, 24
2. Find the median (second quartile, Q2) of the data set. In this case, since we have 8 data points, the median is the average of the two middle values:
(9 + 10) / 2 = 9.5
3. Split the data set into two halves:
First half: 4, 5, 7, 9
Second half: 10, 14, 16, 24
4. Find the median (Q1) of the first half by using the same process as step 2:
(5 + 7) / 2 = 6
5. Find the median (Q3) of the second half:
(14 + 16) / 2 = 15
6. Calculate the interquartile range by subtracting Q1 from Q3:
15 - 6 = 9
Therefore, the interquartile range of the given data set is 9.
The correct answer is D. 9.
