Question

Find the median from the following numbers: 15, 8, 7, 5, 4, 1, 9, 16 group of answer choices a. 7.5 b. 7.0 c. 8.0 d. 8.5

Answer 1

A &.5

Explanation:

Arrange the data points from smallest to largest.

If the number of data points is odd, the median is the middle data point in the list.

If the number of data points is even, the median is the average of the two middle data points in the list.

Answer 2

a. 7.5

Explanation:

The median is the middle number. We can't get down to finding the median unless the data is arranged in ascending order.

Let's arrange our set from least to greatest:

15, 8, 7, 5, 4, 1, 9, 16

Rearranged → 1, 4, 5, 7, 8, 9, 15, 16

We have two middle numbers (7 and 8) so, we average them:

(7 + 8)/2 = 15/2 = 7.5
