Using MassHunter 10.2 and Report Builder 10.2.
Is there any way to report mean/stdev of a column?
Variables declared in Report Builder template expressions do persist through the report, so with a little bit of prep work in unused cells it is possible. I have attached an example template provided by hexatriene that calculates the RSDs of 8 replicate injections. This code is written so that if less than 8 injections are given it will not output a meaningful result. The expressions can be adjusted to work however you like and this should give you some idea of how to have a report calculate a statistical result for a column.
For the example I modified the shipping VOA data set and used one of the ISTDs to demonstrate, so the IDL fails. But it demonstrates what you can expect the unmodified template to produce.
