AVerage Part Weight

What is the standard or a good rule of thumb for finding weight stablity in the Average Part Weight? Is their a formula based on how many parts that go into a container? That will tell you how many parts you should count to get a stable number without having to count the full box quantity?

Example of my actual container quantity and the last APW some based on 100 or 500 peices:

P/N 57, 25,000pcs, APW .000621
P/N 04, 36,000pcs, APW .000499
P/N 01, 1,000pcs, APW .01044

Just trying to find a good quantity instead of having to count the full box quantity.

Thank you for any ideas,

:bonk:

LMO,

Maybe you'd get more help from the Cove stats gurus if you gave some more info.

How accurate does your count need to be? If you sent 24990 or 25015 instead of 25,000 would this be a problem?

What was the std. dev. of the weight?

Counting scales I have used in the past have asked for about 30 samples from the population to get a baseline, then they estimate the total qty. based on this. Try some experiments using different quantities of samples for the avg. weight and see how accurate it is vs. how accurate you need to be.
