In which of the following scatterplots, the value of one dimension can be used to predict the value of another, as accurately as possible?
Explanation:
The question can be answered by looking at the scatterplot, which is on the left hand side of the diagonal.
Option (a) is weak as the scatter is dispersed all over.
Option (b) is very close, but some dispersion can be seen away from the trend line.
The scatterplot in the option (d) is dispersed as well and hence it cannot be right answer.
The scatterplot in the option (c) is indeed the closest to the trend line and hence it should be the answer, though the relationship is weaker as compared to that in the option (b) (This is because it is curvilinear in shape, while relationship value assumes linearity)
Hence, option (c).
