If we have a group size average GOAL, say .5, are 4 or 5 group sizes, averaged, more likely to meet the goal? Should we shoot 4 groups, or 5?
The variables are n = number of groups averaged, and the long term accuracy, LTA, of the gun/shooter/etc.
Inaccurate guns sometimes shoot small groups, accurate guns sometimes shoot big groups.
A combo with LTA of .1 will (almost) never average over .5; a combo with LTA of 3.0 will (almost) never average under .5.
Combos with LTA < GOAL shoot fewer averages > GOAL with n = 5.
Combos with LTA > GOAL shoot fewer averages > GOAL with n = 4.
I can't figure out how to put the EXCEL workbook that solves for any sets of n and LTA here, email [email protected] for a copy. It solves for standard deviation, and requires NO statistics knowledge to use.
