Based on the particular case of the average impact factor of a subfield versus the impact factor of this subfield as a whole, the difference is studied between an average of quotients, denoted as AQ, and a global average, obtained as a quotient of averages, and denoted as GQ. In the case of impact factors, AQ becomes the average impact factor of a field, and GQ becomes its global impact factor.
