Nope.
Consider, say, this chart of adult male height (no idea if it's actually accurate, that's not really the point): https://4.bp.blogspot.com/_ip4sMYv438c/TRjMhUlQczI/AAAAAAAAA...
The majority are around 5'7" - 5'10".
"Extreme" would be the tail ends, say <5'1" or >6'3".
There's a fair bit between those, that is neither part of the majority nor extreme.
