If 5, 8, 6 and 2 occur with frequencies 3, 2, 4 and 1 respectively. Find the product of the modal and the median number
- A.
36 - B.
48 - C.
30 - D.
40
Correct Answer: Option A
Explanation
Arrange in ascending order
2, 5, 5, 6, 6, ,6, 6, 8, 8
Position of median = ^{N}/_{2} = ^{8}/_{2} = 4th and 5th
∴Median = (6+6) / 2 = ^{12}/_{2} = 6
Mode the item that repeat itself most = 6
∴Product of modal and median number = 6 x 6 = 36
