I’m a novice when it comes to applying statistics to practical applications. Sorry if this has been covered in another post somewhere. I compete in competitions where accuracy and precision is compared between two competitors.
My question is...
How many shots at a target are required to determine the accuracy?
What attributes, factors or terms should we be talking about when comparing one competitor’s results (precision) to another?
Some times competitors take 3 shots and brag about how accurate they are. But I know that it’s the repeatability of that group size that really matters. Sometimes 5 shots are taken and some times 10 or 20 are taken.
I know that precision is dependent on the number of shots taken. A 3 shot group that measures .3” is a lot less impressive than a 20 shot .5” group.
#1) Is there a better number of shots that I should use? Should I include a confidence number (or some other attribute) when comparing group sizes with a larger or smaller number of shots used?
#2) What are the attributes of the number of shots taken vs groups size that we should be talking about? I typically shoot 5 shot groups. I feel that 3 is too little and 10 is too much when running tests.
