1 - Variance calculation with dynamic arrays

Description:

In probability theory and statistics, variance measures how far a set of numbers is spread out. A variance of zero indicates that all the values are identical. Variance is always non-negative: a small variance indicates that the data points tend to be very close to the mean (expected value) and hence to each other, while a high variance indicates that the data points are very spread out around the mean and from each other.

Example: x(input) D = X - Mean D2 9 -11 121 12 -8 64 15 -5 25 18 -2 4 20 0 0 22 2 4 23 3 9 24 4 16 26 6 36 31 11 121 Sum = 200 Sum = 400 Mean = (sum of x) / size where : size = Number of items in the input Formula to calculate the variance: sigma = (sum of D2 ) / size
