.........a local dive "professional" stated, "You do know that (insert agency here) has had more diver deaths, don't you?" That's a pretty bold statement, and I'm looking for figures to substantiate it......
Folowing what Rakkis and others have said, allow me to get nerdy for a moment here ...
As pointed out above, the agency with the highest numbers of people who they've certified can be expected to have the highest numbers of incidents.
So ...
Bare numbers are meaningless. To be anywhere near statistically significant, you need to "
normalize" the numbers to be able to compare them......
Probably the easist way to do this, for example, is to divide [the number of PADI incidents] by [the total number of PADI divers]. Only after that can you compare it to NAUI as [total NAUI incidents] / [total NAUI divers], etc.
-------------------------------
IMHO, however, the information taught by any of the major agencies (PADI, NAUI, YMCA, etc) are so similar for the OW level divers, that the other variables that come with the temprament, condition, and intelligence of the individual divers, the ability of the instructors to TEACH, and on to the decisions to dive, the conditions for the dive, etc probably override any agency influences.
