I frequently need to calculate standard deviations (and standard
errors) in my spreadsheets. I can input the functions manually, but
wonder if it is possible to put a custom standard deviation button
(linked to a macro?) on the toolbar, thereby saving a lot of mouse
clicking. Since it is already done for the "SUM" function, I assume
it is possible to do with more complex formulas, but I can't figure
out how to program the selected cell range in the macro. I would
appreciate any advice.
