This statement is also False.

Example: a set of numbers {1, 4, 100, 100, 100}
the average is 61 and only 2 of the 5 numbers are less than the average. (40%)

  That's false.  Consider the the simple case of a set of 1 element only.

Correct, although when it comes to people it depends on what one defines as average.

Sources? The title was simply an attention grabber.

S.A.M. already proved the statement false.

The only time half the set of samples is below average is in an example like this: 2 2 2 10 10 10, average is 6 and half in this sample are below average.

But because the general statement was based on an "always" assumption it was proven false by S.A.M.
