Since this thread started almost 4 years ago, does that mean the average age is now 78?!?!?!?!?! I hope more yunguns got into the game so the average is not that bad (and I won't feel SO old) .... too soon old, too late smart I always say ....
I'll be 61 in May. I live south of you in Beckley. What is the vehicle you show or own? There's a car club in the Beckley area called the Shadetree Car Club.
I think none of us has got time to wait for that calculation, especially now that the age of the thread itself needs to be factored in, not to mention the accounting for the Elvis's who have left the building.
Statical analysis is something I have had some experience with. That said, one of the important assumptions of any statical analysis is the "continuity of the statistical universe." In this case there is none. There is no way any conclusion can be determined. These data were gathered over almost a four year period with changes in the statistical membership (respondents entered and left). The only conclusion that can be made is an on-going response to a question posed in 2011 is occurring.
