Issues with the LifeStyles study data

[craig_uk]

knite crawlur is pretty close. I just finished my last statistics class (thank goodness). sample size of 300 is quite small to be generalizing for a whole population, but...you're math is wrong...1/300=0.003333...0.3333 would be 100/300

Where I come from 1 out of 100 (1/100) is 1%.

So how is 1 out of 300 equal to 0.00333... %? (surely that is 1 in 30,000).

I'm thinking he missed the % sign after .3333.

1/300 is .003333 as he said. He then goes, "... .333," where I think the % was omitted.

Don't have an explanation but completely agree.
Many major studies are seriously flawed. Even when the flaws are highlighted, many people still quote findings as universal fact.

any time a number is listed in two seperate brackets...that skews results to me
look at the girth chart
5.5" is on two entries

This makes the most sense since all the categegories overlap in both length and girth.

... "Message" might be a better term for what they did to the data.

Actually, I'm thinking that "Massage" would be more like it.

The only possibility I thought of was that the charts were supposed to represent the normal distribution for the entire male population, calculated from the results of the study. But if that's the case, how could the "bell" shape become so distorted around the reported mean for the girth (4.972")? The 4.75" to 5.00" interval has the highest percentage, as you'd expect, but then the distribution dips VERY low for the two adjacent intervals before rising again for the 4.25" to 4.50" and 5.25" to 5.50" intervals. There's no way a normal distribution could take that form. The page I linked to elaborates on this point a little, also.

Girth is harder to come by.
This is why "large and extra large condoms" are for 5.25 & 5.5" girth
6" girth = huge
6.5" & above =gigantic.


this is what it should look like

Anybody else fascinated by the question of what makes a 3+ year old thread resurface from out of nowhere?
