You are correct for non Gaussian distributions. IQ tests appear to be a normal dist. I was not specific enough.
That's the old joke, "If Jeff Bezos walks into a dinner party, suddenly everyone is on average a billionaire!"
Which used to be "Bill Gates", and before that "Warren Buffet". I wonder who will be the next person to fill in this joke. :)
Not exactly, this is sort of true in practice but not true logically. Imagine a population of [1, 100, 100, 100] or a population of [1,1,1,1,999999]. Two examples where the population that is below average exceeds half the population and is below half the population.
But this is just semantics. If the population follows a bell curve and at high resolution standard deviations, what you said is generally true.
