Does anyone know about the hidden statistics function in this calculator? You can enter the variance, mean etc and do some calculations? I only remember the one where u press the well-known "shift-on-hyp" combination, then press mode to enter SD mode, then press shift > store > 1. Used to use it when i was in junior college but i forgotten everything
