Multiple Choice

The data in the following scatterplot are from a small data set:

A) The overall correlation is positive, but this value is meaningless because the data show two distinct patterns depending on season.
B) The overall correlation is negative, because the open and solid circles display a negative trend.
C) The overall correlation is near zero, because the open and closed circles display a negative trend, but the trend from the open circles to the solid circles is positive, making the trends cancel each other out.
D) The overall correlation is negative, but this value is meaningless because the data show two distinct patterns depending on season.
