BP317 Number of enclosed black circles varies in correlation with enclosing circle outline size vs. not so.
(edit; present; nest [left/right]; search; history)
COMMENTS

This is a Bongard Problem about comparing something discrete (number) with something continuous (size).


The inner black circles vary in size randomly. (This forces the solution to be about the discrete number of black circles instead of their combined area.)

BP320 The numbers of dots in the two clusters are approximately equal (log scale) vs. the numbers of dots in the two clusters differ a lot.
(edit; present; nest [left/right]; search; history)
COMMENTS

The point is that, on the left, the two groups look about the same to the eye at first glance.


In left examples the numbers are off by a factor of 7/6 or less vs. in right examples the numbers are off by a factor of 2 or greater.
