What is the difference between the mean and the median of the data set?

{22, 8, 10, 18,12, 20}

A) 0

B) 2

C) 4

D) 6

Your answer is 0 (zero).

Step by Step Explanations:

For mean:

1. Add all the numbers; which is 90

2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15

3. Your mean is 15

For Median:

1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22

2. Find the middle number (s), which are 12 &18

3. Add; 12 + 18 = 30

4. Divide; 30/2 = 15

5. Your Median is 15

So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0
