Actually, they represent quite a minority.
You don't know how statistics work do you? If you take 3000 out of 30000 buyers, and base a judgement on the views of those 3000. It would be a good indicator of what the rest of the buyers would say. You take common comments and evaluate the overall judgement of the product in question.
My sentence was they REPRESENT a large portion, and not THEY ARE a large portion.
No you said "The members on here represent a large portion of views." They don't. They represent a small portion of views.
I do know what statistics are this what you said has nothing to do with statistics.
The members on car forums for ANY make of high volume car represent the MINORITY of owners. They are also far more likely to be "car enthusiasts" so their views and opinions aren't even a valid representation of the majority. So to use sampling (which is what you're referring to) as a valid way of measuring something, you need a properly cross-represented sample. Not a very specific niche of people.
That is my opinion
and it is wrong. You clearly don't understand and aren't interested in my explanation. I was going to go into even more detail about statistical analysis and how sampling actually works, including the cross section of demographics you need etc, but it would be wasted.
