Hi

I'm hoping that some kind person can help me with a question regarding the calculation of standard deviation;

-after calculating the initial deviation figures, some of them are negative. When squaring up a negative figure, do you ignore the negatives? Or, do you observe it and therefore diminish the number further?

For instance, with a deviation of -5.95, would you multiply -5.95 x -5.95, or 5.95 x 5.95, or even -5.95 x 5.95?

I know that this is, in all probability, an amazingly stupid question, but do you know the feeling when you've been staring at something for 4 hours...........

Thanks, in hope!
