Calculating distributions
You can calculate a distribution to fit the Normal Pdf distribution model.
1. Select the column formula cell (second cell from the top) in column A.

down list:
– X Value: Click the drop-down arrow to choose any list in the
problem to provide the x values for the calculation.
– Mean: Type a value for the mean or click the drop-down arrow to
choose a variable that contains the mean.
– Standard Deviation: Type a value for the standard deviation or
choose a variable that contains the standard deviation.
