Exercise: GPs' incomes

In April 2006 it was reported that some general practitioners (GPs) receive an income of more than 250,00 per year from the National Health Service.

Following this, it was also reported that the average GP income was 94,000 per year. It is not clear whether this was the arithmetic mean or the median income.
