Bad Beat Tests - Pre-flop All-ins - Conclusions

Excepting i-Poker tests, all the tests have shown that the actual number of hands won was very close to the expected number of hands won. In every case the actual deviation was less than 2 standard deviations from the expected value.

The evidence shows that our alternate hypothesis is incorrect for these samples of hands, i.e. the turn and river cards are not biased to favour losing players in all-in situations.

We can therefore conclude that for the games tested cash tables our null hypothesis is correct and that each online poker site tested was fair (with respect to 'bad beats' for pre-flop all-ins) for the duration of the test period.

In some i-Poker hand samples a significant bias was detected - more detailed information can be seen at the i-Poker page.
