Why 30 rounds?
Because it's the Golden Rule for sample size: samples less than 30 have enough sampling error that the conclusive power is often invalid. People familiar with inferential stats know this general rule (which is NOT the same as the true statistical "power" of a sample, which is not worth belaboring here). The approximation of group dispersion as a "normal" distribution seems reasonable to me.
Deleted, no point in kicking a dead horse...
Hmmm. Wouldn't the sample size of 30 be more appropriately applied to the number of groups shot rather than the number shot in a given group?
The individual shots in a group would not comprise a measurement or datum, but a group size formed by that set of shots forms one datum in your sample.
How many shots should be included in a group is still open for debate.
This is a quality postHere is my KAC SR-15 with VCOG optic.
In true INGO fashion. Well done sir!Meh, my PSA, Anderson, DPMS, build is just as gooder, and only cost $350. You're silly for paying more.
