A) 55
B) 52.8
C) 51
D) 59

Accepted Answer

Median is the middle value of a data set when assorted in the order from smallest to largest. In this case, the data can be assorted as 22, 35, 39, 42, 51, 59, 66, 68, 71, 75. Since there are even number of values in the data set, the median is the average of two middle values. Therefore, the median is (51+59)/2 = 55.
