If you're unfamiliar with your calculator's layout, it will cost you some time just learning how to use the functions.

Binary recommends a Casio fx-115MS calculator for this event.

Yep. This is good. My partner(s) and I have been working with the "marble and ramp" experiment.

Heres the easy equation- (The root of (((xi-mean) squared) + ((xi-mean) squared) + ("" until no more inputs) divided by the number of inputs minus 1))
xi stands for each individual input.
Everything is inside a square root sign, and everything inside is over the number of inputs. (I included both of that into the equation)
