how is this a shortcut? i already know how to use a calculator. the point of a shortcut was to find a way to get the standard deviation without having to go through the pain of having to square each individual value every single time! when you're working with 30+ numbers this is unbelievably irritating, calculator or no. this isn't a shortcut!
