The StatisticsCalculator transformer would calculate the standard deviation (not to mention the min, max, mean, mode, median etc) in a workspace.
This transformer uses the @Tcl2 function and SortFactory factory, so for mapping files the best thing would be to copy a transformer from WB and paste it into a text editor to see how it is using TCL.
