Question

Find the median of the data.

12, 10, 14, 9, 8, 9, 15, 15

Answer 1

11.

Explanation:

12, 10, 14, 9, 8, 9, 15, 15

Arrange in ascending order:

8 9 9 10 12 14 15 15

Here, the median is the mean of the 2 middle numbers:

= (10+12) = 11.

Answer 2

11

Explanation:

First, order the numbers in the given set from least to greatest:

8 , 9 , 9 , 10 , 12 , 14 , 15 , 15

The median is the number found in the middle of the given set. If the amount of numbers in the set are even (as in this case), then you will find the mean of the two middle numbers.

In this case, the middle numbers are 10 & 12:

Find the mean. The mean is found by adding all the numbers together and dividing by the amount of numbers there is:

(10 + 12)/2 = (22)/2 = 11

11 is your median.
