In regression tasks, the Mean Absolute Error (MAE) is a critical metric used to evaluate the accuracy of a predictive model by measuring the average magnitude of errors in a set of predictions, without considering their direction. A lower MAE indicates that the model's predictions are closer to the actual values, which is desirable when predicting outcomes such as car prices.

Selecting Model Gamma, because it demonstrates a lower MAE compared to the other model, signifies a better performance in terms of prediction accuracy. This is essential in contexts like pricing, where even small differences can greatly impact consumer decisions and market dynamics.

In contrast, a higher MAE, as seen with Model Delta, implies that its predictions deviate more significantly from the actual car prices, making it a less suitable choice for this specific task. Therefore, using MAE as a basis for comparison is not only acceptable but valuable, as it provides a clear standard for assessing predictive performance in regression models. This clarity reinforces the decision to prefer Model Gamma, aligning with best practices for model evaluation in the context of improving predictive accuracy in car price forecasts.
