Are cars with farther distances logged given additional weight in calculations than cars with smaller distances?
No. Weighting cars based on distance builds on the premise that after driving far enough, every car will achieve the same fuel economy. Therefore, cars with more miles are more “accurate.” This, however, is an incorrect assumption. There is such a large quantity of variables that contribute to one’s resultant fuel economy that no single value can be considered most “accurate.” To best reflect the conditions of a typical driver, a person with ideal conditions is given equal consideration as someone with unideal conditions, even if they have not necessarily contributed an equivalent distance. Also, the median of the sample is used to reduce the influence of outliers.
