As part of data handling in KS3 Maths you will have to analyse the information presented to you. One key part of data analysis is finding the averages, There are three main types of average - mean, median and mode.
The whole point of averages is to find a typical or representative value of a data set. But the method you use can affect your results dramatically. The same set of data can give you a mean value of 4.04, a median value of 9 and a mode of 12. You see how much variance there can be? Depending on your data, you will have to decide which method of calculating averages will best represent the information you have. Judgement is a skill which will serve you well in maths.
See how much you know about averages in this quiz. It deals with mean, mode and median. Can you work the averages out? Can you decide which ones best suit different situations? Read the following ten questions carefully and think hard about your answers. Let's see if you can get an above average score of 10-out-of-10! Good luck.
