Mean, Median, Mode And Range Prove It

MEAN:
Example: 5, 3, 3, 1, 6
1.) You would add up all the numbers.
5+3+3+1+6= 18 
2.) Now count up how many numbers there is.
3.) In this case there is five numbers.
4.) Now divide five (the amount of numbers) with eighteen (the numbers all added together) 
Eighteen divided by five= 3.6
MEDIAN:
Example: 5, 3, 3, 1, 6
1.) You have to order the numbers from smallest to largest.
1, 3, 3, 5, 6
2.) Now find the number in the middle.
1, 3, 3, 5, 6
3.) That is your answer!
MODE:
Example: 5, 3, 3, 1, 6
1.) Find the number that appears the most in the pattern.
5, 3, 3, 1, 6
2.) That is your answer!
RANGE:
Example: 5, 3, 3, 1, 6
1.) Find the biggest number.
5, 3, 3, 1, 6
2.) Find the smallest number.
3.) Take away the smallest number from the biggest.
One minus six= Five
4.) That's your answer!
