You fit two linear regression models for the same data, where the first one gives an RMSE value of 3.78, and the second returns a value of 6.33.

R-squared values in the train and test sets are as follows:

Model | R-squared (on train set) | R-squared (on test set) |

First Model | 0.85 | 0.61 |

Second Model | 0.74 | 0.72 |
