calculated by adding all the data point values together and then dividing the total by the

number of data points. Mathematically this formula can expressed as illustrated in the

following picture:

Where:

av the calculated arithmetic mean

n the number of data points to include in the calculation

a data point to include in the calculation

For example, if there were 5 data points to calculate the arithmetic mean of and they

were, 12.3, 15.9, 16.2, 14.7, 14.9, then the arithmetic mean would be 14.8.
