mean,median,mode and range prove it.

mean:
Example: 5 4 8 2 1
1)Add up all the numbers.
5+4+8+2+1=20
2)now count up all the numbers there are.
there is 5 numbers.
3)divide 20 by 5 and that's your answer.
20 divided by 5 =4

median:
Example: 9 7 2 6 4 
1)order the row of numbers from smallest to largest.
2 4 6 7 9
2)the number in the middle of all the numbers in the answer.
2 4 6 7 9


Mode:
Example: 2 11 4 31 11
1)the number that is the most repeated in the row of numbers is the answer.
2 11 4 31 11

Range:
Example 2 4 7 10 31
