The first difference square will be calculated as (8.4 - 9.34) 2 = 0.8836, the second square of difference will be (8.5 - 9.34) 2 = 0.7056, the third square can be calculated as (9.1 - 9.34) 2 = 0.0576, and so on. Variance is the spread between data points and is calculated as the sum of the squares of the difference between each data point and the mean divided by the number of observations. Second, calculate the variance of the set.First, calculate the mean of the observed data. ![]()
