Quizplus · Accepted Answer

To find the third quartile, we need to find the median of the upper half of the data set. First, we need to find the median of the entire data set. Putting the numbers in order, we get:

166, 168, 177, 181, 186, 188, 194, 201, 209, 251

The median is the middle value, which is 186. Now we need to find the median of the upper half of the data set, which is:

188, 194, 201, 209, 251

The median is 201, which is the third quartile. Therefore, the answer is B.
