The variance is calculated. Variance is the sum of squares divided by the number of data points.

The formula for population variance is:

|2= to (xi−μ)2n Variance

The variance form for a sample of data is as follows:

Variance (xi−x ̄)2n−1 Variance = s2= s2

Formula Variance

The formula to variate an is the sum of a square difference, divided by the number of data values, between each data point and the mean. The following formulas are used in the calculations of the variance.

 

Divide by size n for a whole population

 

Difference=C2 = Difference=1(xi−μ)2n

Divide by sample size minus 1, n – 1 in a sample population

 

Variance=s2=to be considered as one (xix ̄ ̄)2n−1

The square root of the population variance is the population standard deviation.

 

Standard population deviation = Ţ2− assets

The standard sample deviation is the quadratic root of the variance calculated for a data set.
