Consider the following dataset: 22, 29, 31, 30, 22, 24, 18, 20, 25. What is the third

quartile's value? Round to the nearest tenth if necessary. (1 point)

1 answer

To find the third quartile, we need to first arrange the data in order:

18, 20, 22, 22, 24, 25, 29, 30, 31

The third quartile is the median of the second half of the data set. In this case, the second half starts from 24 and ends at 31. The median of the second half is (24+25)/2 = 24.5

Therefore, the third quartile's value is 24.5.
