In schools, for example, it is usually expressed as the number of students per teacher. In any case, ratio means comparing one number to another, so staffing ratio compares number of students to number of staff (teachers).

The numerical average of a group of numbers is the ratio of the sum of group of numbers to the total amount of numbers. This is also known as the mean.
