[Informatics] How many records for a data set?

[Laurie Savage]

There are some statistical rules that describe what levels of confidence
you can ascribe to inferences based on the sample size. Any good statistics
text will help you there. I suggest you Google "sample size confidence
limits" or something similar.

A common fault is to make a sample too large for the question.
