Description Usage Format

This dataset contains selected varaibles, and removes vehicles with incomplete data (e.g. no drive train data). These data are a subset of the package fueleconomy, with only the 2015 model year and the vehicle class has been simplified. The column Efficiency was calculated by calculating median City MPG and evaluating if a particular model was in the upper or lower half of the City MPG.
