What is standard deviation shortcut formula?

A Direct Method to Calculate Standard Deviation Use the formula ∑X/N to calculate the arithmetic mean. After this, we calculate the deviations of all the observations from the mean value using the formula D= X-mean. Here, D = deviation of an item that is relative to mean. It is calculated as D = X- mean.
