Good Afternoon,
There was a discussion in my Compliance department regarding samples sizes when doing Compliance Reviews. Not everyone in the team was choosing a sample size consistently. One member of our team suggested following the FRB's sample size chart (Below). In my opinion this is very excessive since we frequently have population sizes over 10,000. Does your bank have a sampling methodology that you guys follow that is different than this? Thank you.
Number in Population Minimum Size of Sample Maximum
Under 99 20 or total population if smaller than 20 20
100 - 299 20 plus 10% of number above 100 40

500 - 749 54 plus 6% of number above 500 69
750 - 999 69 plus 5% of number above 750 82

2,000 – 2,999 122 plus 3% of number above 2,000 152
3,000 – 4,999 152 plus 2% of number above 3,000 192

10,000 or more 267 plus 1% of number above10,000 267
