Inspired by swuehl's response here: Help with Standard deviation Full population No... | Qlik Community I thought it make sense to share a way to calculate population standard deviation as QlikView's Stdev() seems to be a sample standard deviation. The difference between the two becomes negligible as the number of data point increases, but there might be a use case to apply population standard deviation for a smaller dataset.
I start with no dimension in an Excel file
If you look at the statestic box, you will see that the standard deviation will show the sample stdev number
Also, when you use =Stdev(Data1), it will show the same number as above. In order to get population stdev, all you need to do is to multiple the standard deviation with this
