G'day
I've got a Abacus SX-II MATRIX a scientific calculator. For a test that is in a few weeks, the ability to calculate standard deviation off your calculator is required.
I can't find any instructions on how to do it.
There's plenty of other guides to other SD calculations on other calculators but not this specific type.
Would anybody have any idea how to do it on this specific one?
Any help would be greatly appreciated!!
Cheers
