Random Skew Vs BiasReply
I've read that there are formulas that mathematicians can use to calculate the parameters of randomness and bias of any event. I would imagine the lotteries audit their drawings and prizes payouts and investigate whenever those events are not within the expected parameters. When PowerBall had all those 5of5 wins last year it triggered an investigation that ended at a fortune cookie factory in New York.

Standard deviation testReply
Don't worry, as far as the lottery goes ...and as far as we players are concerned......... it's just a measure of a bunch of existing data by someone trying toaudit the lottery game for true results. Nothing to do with anything future. Unless they were to leave it with some sort of bias variances. LOL Computer draws ....would be the biggest target for such a measure as far as we are concerned here. I think the State Games should post the audit results of those computer draws on th
