# Council Directive of 20 January 1976 on the approximation of the laws of the Member States relating to the making-up by weight or by volume of certain prepackaged products (76/211/EEC), Division 2.3.2.2

Extent: E+W+S+N.I.

and the estimated value of the standard deviation s by the following calculation:
the sum of the squares of the measured values: ∑ i = 1 i = n x i 2
the square of the sum of the measured values: ∑ i = 1 i = n x i 2
then 1 n ∑ i = 1 i = n x i 2
the corrected sum SC = ∑ i = 1 i = n SC = ∑ i = n x i 2 − 1 n ∑ i = 1 i = n x i 2
the estimated variance: v = SC n — 1
the estimated value of the standard deviation is: s = v
