This is an example of an accretion measure, because Professor Smithson is collecting data on what radio stations people actually listen to based on the cars that are brought in for repair. It is not a Nielson rating, which is a more formal and comprehensive survey of radio listenership, and it is not an erosion measure, which involves observing a declining trend or phenomenon over time. The ecological fallacy refers to drawing incorrect conclusions about individuals based on data collected on a group level, which is not relevant in this scenario.
