Answer:
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
