Assume you found a wheel, where you spot factors that make it appear biased in a section.

you start collecting data and fair enough those numbers appear to fall more often.

Entered in RA software I get 3+SD on the biased chart after 200 spins.

now looking at the chi square test.

if I interpreted the instructions on this math site(HMD 436) correctly then i need to compare all numbers that have fallen and assume its a random wheel. If CHI square is very high or p% very low then biased becomes more and more likely.

my question is do you guys even use the chi square analysis and if so what is the bench mark you personally want to have minimum.

obviously more chi square and SD is always better but at least a ball park answer would be helpful.

thak you
