You're too easy to provoke, Wouter - it's almost no fun.

You also don't know the difference bewteen an assumption and an inference:

Assumption: Something taken for granted or accepted as true without proof.

Inference: The act or process of deriving logical conclusions from premises known or assumed to be true.

I made no assumptions in my statements, other than a healthy majority of catsailor.com regulars are in the SE United States.

The inference is that the more someone posts on catsailor.com, the more likely they are to vote on this. The numbers quoted are merely reference points in relation to the population of catamaran sailors who care enough to vote on this.

Most significance tests assume you have a truly random sample. If your sample is not truly random, a significance test may overstate the accuracy of the results, because it only considers random error. The test cannot consider biases resulting from non-random error (for example a badly selected sample).

That's my second point.



No, you're an irritating Dutchman because you don't know [censored] about statistics and are too proud/arrogant/egotistical to admit it.

Oh, and by the way - I haven't looked at the results, because frankly - I don't care. I've got more than enough events to go to. Starting this weekend, I'll be competing in an event nearly every weekend until October. And I'd rather be on the water than looking at a computer screen, making a point in an argument that in the grand scheme of things, doesn't mean squat.
