In Mathematics, the variance is a measure which can be calculated from the set of data. It can be calculated by taking the average of the squared difference from the mean. To find out the variance, follow the below procedure:

Step 1: Find out the mean for the given set of data

Step 2: For each number, subtract the mean and then square the obtained result

Step 3: Finally, work out the average of those squared differences.

For example, 5, 6, 7 are the set of data

Step 1: mean = (5 + 6 + 7)/3 = 18/3 = 6

Step 2: (5 – 6) 2 + (6 – 6) 2 + (7 – 6) 2 = (-1) 2 + 0 + (1) 2

Step 3: (1 + 0 + 1)/3 = â…” = 0.667
