Figure 1. ‘Blob plot’ illustrating an example set of values and showing the mean If there is variation in readings when they are repeated, it is best to take many readings and take an average. An average gives you an estimate of the ‘true’ value. An average or arithmetic mean is usually shown by a symbol with a bar above it, e.g. x (‘x-bar’) is the mean value of x. Figure 1 shows an illustration of a set of values and their mean value. Example 1 shows how to calculate an arithmetic mean. | How many readings should you average?
