Question

A list of numbers is shown; 1 2 3 4 5 6 7 8 9 10

what is the median

A.2

B.4

C.9

D.10

Answer 1

5.5

Explanation:

We have a list of 10 numbers (n = 10) ordered from lower to higher.

1 2 3 4 5 6 7 8 9 10

The median is the value separating the higher half from the lower half of a data sample. Since n is even, there is no middle value and the median is defined as the mean between the two middle values, in this case, 5 and 6. Then,

median = 5 + 6 / 2 = 5.5
