`Outlier` is the number that stands out from the rest of the set. If it is less than the usual numbers it would mean less books rented, if it is more than it would be a large amount of books rented.

ok...I think I understand @563blackghost.....would it be B or C? because I see 2 outliers

563blackghost · Answer

That is correct there are two outliers. Now since it is 9 and 10 and the usual numbers range from `80 - 99` are `9 and 10` less or greater than the usual numbers?
