Averages
Subjects / Maths / Data Handling
We can collect results from different areas, such as experiments or questionnaires. To look for trends or patterns in results, we look for a result that represents the data. This is called an average. There are three different types of average - the mode, the median and the mean - and each gives you a different view of the data. The range is often grouped with these values. It is not really an average, but it does give you a view of the data. This title considers how to work out averages, both from lists of data and from frequency tables. Chapter Three looks at how we work out the averages of grouped data. For those sitting the Higher level paper, Chapter Four considers comparing averages of several sets of data. You can then test your understanding with some questions on averages.
