Talk:Ape index/Archive 1

December 2007
Scientific evdence actually shows that while there may not be an ape index, children who are more physically active tend to be taller. I am not sure if this is off topic, but I think it has to do with this subject.Jourdy288 (talk) 20:16, 17 December 2007 (UTC)

Hoax
Wikipedia is not for things made up one day. References are bogus: two of the links don't work and one is not public. Intromission (talk) 10:47, 1 September 2009 (UTC)


 * No, it seems to be real enough. There are a few references in the British Journal of Sports Medicine and similar journals, along with some book references. I'd normally be a bit iffy still, but a few papers have found that it is statistically significant in terms of performance in at least one sport, so given that I'll add a few references once I get an internet connection that is a tad higher tech than two computers with a length of wet string running between them. - Bilby (talk) 12:01, 1 September 2009 (UTC)

any statistics?
I'd like to know how likely a given ratio is. I've seen a study that found average ratio (height/arm span) to be from 0.9711 - 0.9816. In another study there was a very different range of 1.06-1.07 for the inverse correlation (about 0.93-0.94), but it included children as young as 7 to elderly in their mid 70s. Also 82.6% of all people have an arm span longer than their height.
 * Just based on that data, it seems safe to assume that 0.97635 +- 0.02365 covers 65.2% of the population, about the first std dev.

What I can't find is the bell curve for frequency to index. Is ~0.86 (Sony Liston's supposed arm span) just unusual or clinically unusual - like a developmental problem? Is ~0.95 (Michael Phelps example from the article) still fairly normal or not? --108.28.13.107 (talk) 13:32, 30 September 2011 (UTC)
