Under a standard bell shaped curve, where most of your shots occur at the apex of the curve, SD is a measure of how far off from the apex of the curve you can expect your shot to be. For example, 1 standard deviation brackets a small area on both sides of the apex, while 2 standard deviations brackets a larger area etc..

The lower the number, the better off you are, as far as consistency goes.
