HLK0001 Posted August 6, 2016 Report Share Posted August 6, 2016 I've tried the spreadsheet method but the standard deviation doesnt seem to be correct? Or maybe I've done it wrong. Could someone please explain how to get the standard deviation on TI NSPIRE? Reply Link to post Share on other sites More sharing options...
