Please, and thank you in advance!

most people would just use a computer. excel can do it.

Yeah, especially during examinations.

My thoughts exactly.

Maybe, if they were doing it at home. But during General Mathematics classes (where you don't have access to a computer) and examinations, such as the HSC where you are not allowed a computer, but you are allowed a calculator, being able to work it out accurately on a calculator becomes an important skill for General Maths students

Yes i know that General Maths students will most likely need to know how to do it on a calculator.

I was just expressing my view, the fact that it is so stupid to teach such outdated technologies such as Graphics Calculators. You will never see a Mathematician, Engineer or Scientist reach for their calculator to do SD, they will either use a statistical package such as Matlab, or program the SD routine into their own computer program. Hence I feel that it is stupid to teach students how to do it on a calculate, just teach them the principles behind it.

See this document about using the Casio FX82MS, it gives instructions on how to use the calculator, including working out standard deviation.
