Question

What is the difference between the mean and median of set S = {2, 4, 6, 7, 7, 13, 18, 92}?.

• A. 10.125
• B. 11.125
• C. 11.625
• D. 10.875

Answer 1

Answer:

C. 11.625

Sum of the numbers = 2+4+6+7+7+13+18+92 = 149 So, mean = 149/8 = 18.625 Median = 7 (frequency of occurence = 2) Hence, difference = 18.625-7 = 11.625.
