[QUOTE="dsculley, post: 1172811, member: 77514"] I used the standard deviation function in Excel. I just ran it again and got the same result. Many chronographs will calculate it for you. My example was an extreme range. Statistics can be used in lots of ways in shooting. If you don't have it, get the Berger reloading manual and read Bryan Litz's section on statistics. My point was that extreme spread is valid only for that string. Standard deviation models the entire population and can be used to determine your expected extreme range over the entire population.
