Mean: The average or the center of the value. To find this, you add up all the numbers and divide by how many numbers there are. 
Example: 3, 4, 5
3+4+5 = 12. 
There are 3 numbers.

12/3 = 4. The mean is 4

Median: Median means the middle value. You place the numbers in order and locate the middle value. 

Example: 5, 4, 3 -> 3,/ 4,/ 5. Middle number 4.

Mode: Place the numbers in order then count how much each number appears. The number that appears the most repeatedly would be the mode.

Example: 3, 4, 4, 4, 5, 5. 

The mode would be 4.

Range: Locate the highest and the lowest values of the given set and subtract the smallest to the largest.
