Calculate the variance (S2) and the standard deviation (SD) of the seed
weights. These values give you a sense of how variable the data in a particular set of measurements actually are.
Variance is calculated by subtracting each individual value (xi) from the mean (X), squaring it and adding all of these squared deviations from mean together. The total is then divided by N-1.
S2 (variance) = (X-xi )2
N-1
