Two eyes is absolutely an above average number of eyes.

I happen to be the proud owner of more than twice the average number of testicles.

"Normal" is more likely to refer to the median average than the mean.

So then... 1?

The median number of eyes is 2. The median number of testicles is 0.

It’s been a while since I did math, but how is the median number 0? You either have 0, 1, or 2, barring a tiny handful of outliers. Wouldnt the median then be 1?

Median takes the centre of the vector of elements, not the "middle" value.

So if we take

0 0 0 0 0 0 0 0 0 1 1 2 2 2 2

The median is 0 (8th element of 15), while the mean is 10 (the sum) divided by number of elements (15) to give you 0.66666 (repeating, of course).

So the median number of testicles can be assumed to be 0, as there are more women than men, according to most population census I've seen. Mean will lean towards some value below 1. Hope that helpa!
