Data Validation

[mrfritz44]

Our Internal Audit department once had a slide rule that calulated the percentage of certainty for data validaiton over a given sample. I cannot for the life of me find and equation to use for my own validation.

Does anyone have that equation or could you point me in the right direction for data sampling?

Thanks,

Fred
