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.

Positive correlation vs. negative correlation.

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 MY13 does not fit on either side because when the X value increases, the Y value stays the same.

Example MY14 does not fit on either side because there is no correlation.
