Question for for Data Science for Python
In a certain predictive study, a trained predictive model has the score of 0.50 when applied to the training dataset and the score of 0.98 when applied to the testing dataset. Which fact is true about the study?
The model is performing better than a randomly fllipped coin, but still is not perfect.
The study results are very unrealistic. There must have been a mistake in the study setup.
The model is overfitted and shall be trained on a different dataset or with different features.
The results are typical, there is nothing specific about this study or the model.
