Question

A researcher finds R squared = 0.95 for a model predicting crop yield from rainfall. What does this suggest about the model?

Accepted Answer

The model fits the data very well; rainfall explains most of the variation in crop yield.

Answer

The model fits the data poorly; rainfall is not a good predictor.

Answer

There is no linear relationship between rainfall and crop yield.

Answer

Rainfall explains only a small portion of the variation in crop yield.
