>>2278282What he's probably trying to say is that there's potentially a large size variance given the diverse gene pool. This means one or more of the following:
1. the data only comes from few selected regions / demographics and isn't fully representative
2. it comes from all regions, but some have literal horse dicks and other have micro-penises
3. there isn't really much of a deviation between different populations
From what I've hear about most penis studies 1 is often the case, because a lot of people just don't like their dicks measured.
