Where x takes on each value in the set x is the average statistical mean of the set of values and n is the number of values in the set. The command to find the population standard deviation in excel is stdevp values and in this case the command is stdevp a2 a6 which gives an answer of 0 49.

In the example shown the formulas in f6 and f7 are.
