A measure of average is a value that is typical for a set of figures. Finding the average helps you to draw conclusions from data. For instance, finding the average number of sales in a given period can help a business make decisions about their stock levels at different points in time. The main types are mean, median and mode. Where a data set is large, a frequency table can make it easier to calculate averages. Students will therefore learn how to use a frequency table to calculate the mean of a data set.
