Average can simply be defined as the sum of all the numbers divided by the total number of values. Average is usually present as mean or arithmetic mean. Mean is simply a method of describing the average of the sample. Average can be calculated for any discrete numbers where it assumes uniform distribution.

Subtract the mean from the data for which you want a standard score. In the example, 28 minus 24 equals 4. Divide the difference between the data and the mean by the standard deviation. In the example, 4 divided by 5 equals a standard score of 0.8.

The AVERAGEA function returns the average (arithmetic mean) of a group of supplied values. The key difference between AVERAGEA and AVERAGE is AVERAGEA will also evaluate the logical values TRUE and FALSE, and numbers represented as text when when they appear in cell references, whereas AVERAGE just skips these values.

Find the absolute difference between two numbers: |20 - 30| = |-10| = 10. Find the average of those two numbers: (20 + 30) / 2 = 50 / 2 = 25. Divide the difference by the average: 10 / 25 = 0.4. Express it as percentages: 0.4 * 100 = 40%

A kind of average. To find the harmonic mean of a set of n numbers, add the reciprocals of the numbers in the set, divide the sum by n, then take the reciprocal of the result. The harmonic mean of {a1, a2, a3, a4, . . ., an} is given below.
