99, 100, 105, 104, 102, 105, 105, 121, 104

What is the median IQ score for this sample?

A.102

B.104

C.105

D.110

Answer 1

To find the median, we first need to arrange the data set in ascending order:



99, 100, 102, 104, 104, 105, 105, 105, 121

Since there are nine values in the data set, the middle value is the fifth value, which is 104. Therefore, the median score for the given data set is 104.
