Calculate Mean, Median, Mode and Range

Walt: Explain/calculate mean median, mode and range using a simple set of data.


I have got to 100 on both of theses activities and can calculate mean, median, mode and range easily.
Here are some examples:

First I ordered the numbers: 
2, 3, 3, 4, 4,5, 7
Then found the middle number. 
Here is an example of doing it with a bar graph. 

To figure out the mean I need to count the numbers up. The total is 28. Then divide 28 by the total of bars or numbers. 28/7 = 4. The mean is 4. 

My Next step is to set a new maths goal.
