Quote from PSO website...
"There is also a common misconception that there are more bad beats dealt online than in the live game, but this is not true. Statistically speaking, they occur at the same frequency whether you play online or in a casino, but because you can play more hands per hour online, the probability that players will experience what they perceive to be bad beats will inevitably increase."
This is only half true
The Introductory multiple choice answer is also incorrect on this
Whilst it is true that players see more bad beats per hour online due to more hands being played, this is most certainly not the only reason why players receive more bad beats online
More bad beats DO occur online because online poker players are looser and chase far more often (especially in Freerolls and low stakes cash games and low buy-in tournaments)
