A great way to teach averages.
My favourite way to teach how averages aren't always the perfect metric is:
My favorite is averaging testicles and including both sexes.
The average person has less than one testicle
Is that true? The sex ratio I generally see quoted is 101:100 or 102:100 male:female. Unless more than that number of men are missing testicles.
For various reasons, yes, many are missing one or more testicles
I'd say testicular cancer and castration, voluntary or not, account for many of that number
Right, but is it more than 2 missing testicles per 102 men? Because that's what it would take to make the average less than one
Well, the numbers seem to say yes
What numbers, because while it's not exactly easy to google for, the numbers I'm seeing don't line up with that. Undescended testicles are relatively common, but that's fixable by surgery and they aren't missing, while testicular cancer, surgical castration (not chemical), and transgender surgeries all seem to account for far less than 1% of the population.
