RMSE (Root Mean Squared Error) is a metric that tells you the deviation of the predicted values by a model from the actual observed values. So, since it is a sort of error term, it is better to have a low RMSE. Notice that the RMSE for the first model is lesser than the second model. So naturally, this model would be better than the other.<\/div>\n","tip":"","notChosenFeedback":""},"text":"

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. which of these is a better model?<\/p>\n"}
