The F-test measures how much the model has improved the prediction of the outcome compared to the level of inaccuracy of the model. It assesses the significance of the overall fit of the model by comparing the variation between the means of the groups to the variation within the groups. A high F-value indicates that the model has a significant effect on the outcome.
