I wonder what level of significance their
statistics are set for? There’s something like
100,000 candidates these days, or is it 200,000.


A 5% alpha level would imply that 2500 - 5000
people might be false positives (assuming a single
tail). A 1% alpha level would imply 500-1000
people might be false positives.

It’s fine to use statistics for screening for
possible cheating, but there’s got to be other
types of evidence before one can summarily suspend
people.

I understand that this is a private organization
and so CFAI can more or less do what they want,
applying whatever standards they feel, but surely
it can’t be good to say… Please take our test,
and by the way, we’re going to throw about 2.5% of
you out each year and accuse you of statistically
cheating.
There wouldn’t be near the many false positives after taking proximity into account. Similar results on a test taken in Dallas and one in Chicago wouldn’t factor in.
