There is an ISO Standard on Statistical Sampling developed through AIIM, 
Though I have not looked at it in years, it is probably what you are 
looking for.  As Marc says, you need to consider the use of the images, 
what your Acceptable Quality is and then you can use the tables in the 
standard to determine your sample size.  Understanding statistics would 
help, which I don't claim.  One of the key factors to consider is the risk 
when choosing you sampling and of course the COST of sampling.

I agree with previous replies about standards and guidelines.  But I'd 
like
to add that whether you need 100% verification or sampling depends also on
the nature of the project. 

If the project is to convert retrospectively some collection of records 
that
will not necessarily be looked at in the immediate future, then you need 
QA
of some sort, as advised in the other responses.  But if the project
involves all the record images being looked at quickly - usually for
indexing or for some other workflow step - then a separate QA step is
probably superfluous, as any defective scanning will be noticed as a
by-product of the process.

Hello,

I have some folks that are looking at an imaging project, using Image Now.
Any experts out there? i would love to tap your brain. They are also 
looking
at sampling rather than verifying every image (my recommendation is to
verify every image). Any thoughts on sampling?
