### 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.
