30 kwi 2015 · Calculate the mean by adding all the numbers together and dividing by the total number of numbers. For example, let’s take a set of test scores from a math class of nine students. The scores were: 65, 95, 73, 88, 83, 92, 74, 83, and 94. To find the mean, add all these scores together. 65 + 95 + 73 + 88 + 83 + 92 + 74 + 83 + 94 = 747.
Mode, median and mean are three types of average. Find out how to calculate them and the range of numbers in this KS2 Primary Maths guide.
