Abstract
In recent years, car users have been provided with a service for managing fuel economy data by posting the fuel supply and travel distance to the WEB at every refueling. If there is no mistake in the contribution data, actual fuel economy will be given to the user. For an analyst trying to utilize a lot of refueling data, some consideration is required for the reliability of the data and the statistical bias in the contributors. In this research, we report the results of actual fuel economy analysis using user contributed data for one year of micro vans nationwide.
