When the Indianapolis Colts won the Super Bowl, the numbers on the jerseys of the active players were 29, 41, 50, 58, 78, . . ., 10 (listed in the alphabetical order of the player's names). Does it make sense to calculate the mean of these numbers?
It does not make sense to calculate the mean of these numbers because they are nominal values only and hold no quantitative value. The numbers are only used to easily identify all of the different players on the pitch and do not measure or count anything.
