Question

Suppose a set of data contains just two data items. If the median is w, the mean is x, and the mode is y, which of the following must be equal.

a. w,x, and y

b. x and y

c. w and x

d. w and y

Answer 1

If you have an even number of data items, the median is calculated by taking the average/mean of the middle two numbers. Since this set only has two items, taking the mean of the middle two numbers is the same as taking the mean of the entire set, so the answer is C.

Hope this helped!
