Printing - Standard Methods for the Examination of Water ...

Because no measurements are repeated an infinite number of times, an estimate of the mean is made, using the same summation procedure but with n equal to a finite number of repeated measurements (10, or 20, or. . .). This estimate of µ is denoted by x. The standard deviation of the normal distribution is defined as σ = [∑(x−µ)2/n]1/2 ...
