The mean

The mean is the most common measure of average. If you ask someone to find the average, this is the method they are likely to use.

Kieran's results were:

9 13 9 11 9 13 11 9 10 8 11

Example: 9+13+9+11+9+13+11+9+10+8+11= 113

113/11 = 10.27

The median

The median is the middle number. To calculate the median of any set of numbers, you need to write the numbers in order.
