An average is some sort of middle or typical number. There are three types; mean, median and mode.
The mean is the answer when you add up all the numbers, then divide the answer by however many numbers there are.
The median is the middle number – remember to put the numbers in order.
The mode is the most common number (speak in nice posh voice – mode sounds like most!)
Range is the biggest number take away the smallest number.
