Some thing to think about

Don Kennedy · 04-10-2013, 10:35 PM

Is any one on here a statistician . I would like them to do a bell curve with racers Reaction times and see if any racer is out side of the bell curve > just curious

Don,

If you can supply the data I can do the analysis.

Don , I'm outside the bell curve , on the red side . I thinks it's a great ideal and would love to see it .

Ricky Baehr and I did our stats on DRR a couple of years ago, and the distribution looked pretty similar if I recall. You could probably do something with 1320go.

I would like to see a comparison of some racers to others and see where they are in the bell curve or out of it. lol

Everyone falls within the "bell curve" .The bell curve(from my nightmarish memories of statistics in orthodontic grad school) is a result of graphing the distribution of a measurement such as average reaction times of different drivers. A natural distribution of a measurement produces a bell shaped curve when you "connect the dots". I believe the question to ask would be: Where do average reaction times of different drivers fall on such a graph?" In any case, great topic Don!

Perhaps what Don wants to know is what is the average reaction time and what is it's standard deviation. From that of course, don would be able to figure out if he is fast or slow and how far above and below the average he is.

That is one of the two reasons why my nickname for statistics is sadistics; the other reason is that statisticians torture the data until it confesses to what they want them to say, or at least that what it sometimes seems like. When I taught econometrics, I used to have my students read an article entitled let's take the Con of of econometrics; I'd also sometimes refer to the course as econometricks.

A very simple Bell Curve like what Don is proposing only needs data of RT from participants, lets use Super stock from Vegas, how many 001 to 1.99 just use NHRA data. Claude

David, is that where the saying comes from, “the data can’t lie only statisticians”
