Mean-the sum of all data divided into the number of data.

Example:
2,4,5,6,7,8,=32

32 divided by 6=mean:5

Median-the middle number
-if you have 2 middle number find the average

Example:
4,8,2,9,6=2 is the middle number


Mode-most common number

6,4,1,3,2,9,8,8=8 is the mode


8-is the most common number

Range-largest data minus smallest data

Example:6,8,4,9,2,7

2 is the smallest
9-is the biggest

So,9-2 =7 is the range

Good job Gerico! Though you should add:arrange the data in ascending order. You could also add some colour.

Good Job! You should put a picture and maybe some colour like Kristin said.

Yes, I also agree with Kristin and Shaneille. If you add colour and some pictures, it would catch your audiences' attention more. Also, you forgot to mention that there could be NO mode. But other than that, good job Gerico. (:
