COMMENTS
|
All examples in this Bongard Problem are scatter plots. Each dot represents a data point.
"Positive correlation" means that when the X value increases, the Y value tends to increase as well (in the long run), while "negative correlation" means that when the X value increases, the Y value tends to decrease. |

EXAMPLE
|
Example TM4854 does not fit on either side because when the X value increases, the Y value stays the same.
Example TM4855 does not fit on either side because there is no correlation. |

EXAMPLE
|
There are 6 ways of arranging the letters A, B and C: ABC, ACB, BAC, BCA, CAB, and CBA. The string "ABCABACBA" contains each of these as a substring, and would therefore be sorted left. |
