      Standard Deviation σ = √Σ(x – μ)2P(x) To calculate these figures, we should construct a table which looks like the following: x P(x) xP(x) x - μ (x – μ)2 (x – μ)2 P(x) Σ = Σ =

      The standard deviation is the average variation of the data values from the mean of the values and is the most commonly used measure of variation. Note that the values for the standard deviation are different for a sample and a population.

      Compare this to the standard deviation. You can get some sense of why they divide by N-1 instead of N by looking at the extreme example in which you have one data point. Since there is one data point it is the mean, the deviation is zero, squaring it gives zero, and since there is only one data point, the sum of the squares is also zero.
