[QUOTE="Winchester 69, post: 209774, member: 8037"] 1. Average your velocities. 2. For each shot, subtract the average velocity from that particular velocity, and square the difference. 3. Get the sum of the squared figures. 4. Divide the sum by the number of shots. This number is the variance. 5. Get the square root of the variance. This number is the standard deviation. The standard deviation is a measure of error that is useful when working with statistical inference based on the Gaussian distribution (bell curve). Other measures of error, like the extreme spread, may be more practical figures, depending on the application. Nope. . [/QUOTE]
