Answer #1

the question is very open ended , but we shall keep it to statistics context

it is s defined to be the ratio of means of two random variables

Assume there are two characteristics – x and y – that can be observed for each sampled element in the data set. The ratio R is

R = Uy/Ux

For example consider:

A national park is partitioned into N units.

yi = the number of animals in unit i
xi = the size of unit i
Another example might be where a certain city has N bookstores.

yi = the sales of a given book title at bookstore i
xi = the size of the bookstore i
