The Lost continent of

You've found a bug on my site!

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.

How tall would you be,

If you weren't a girl, or a boy?

I'm reasonably tall for a New Zealand male: 188cm (that's six foot two, if you're still stuck in the dark ages...)

What I'd like to know is: How tall would I be if I were a Girl?

Don't get the wrong impression here — I don't spend a lot of time imagining what life would be like if I were a girl. No more than the average man, anyway... It's just that I wanted to see if my very tall female friend would be taller than me, given a fair genetic playing field.

Your Height: cm, or ft, inches
Your Sex: Male

My Female height came out at 174cm, five foot nine. My freind wins: she is 'taller' than me...

About the 'Calculation'

It's a little bit hokey — par for the course, I suppose... I found some data on human heights on the web, specifically the male and female values for mean height and standard deviation.

The webpage simply calculates how many standard deviations away your height is from the mean of your sex, then applies the same metric to the figures for the opposite sex.

Male Female
Mean Height 176.0cm (5' 9") 163.6cm (5' 4.5")
Standard Deviation 5.96cm (2.35") 5.33cm (2.10")

Data from the U.S. Department Of Health And Human Services,
The Center for Disease Control and Prevention.

For example, I am a human male standing 188cm (6'2") tall. The mean for my sex is 176.0cm - I am 12cm taller than the mean, or, almost exactly two standard deviations. The mean height for females of my species is 163.6cm. Two (female) standard deviations from that is 10.7cm. So 'my' height would be 174.3 cm, or about 5'9"...
