Can someone confirm that I'm not just reading it wrong?

I have derived and added the update formulas (only the results) for the unbiased/biased variance. The clearly shown that the (old) second formula which was in dispute was wrong, so I removed it. I have also removed the example which just shows some numbers (was it a weak numerical proof?) and does not provide any insight on how the formulas work. It was not clear wheater the algorithms were for biased or unbiased estimators, so I added comments on it. BurkayDonderici
