Suppose you take a survey of all the schools in your state. What would you expect the relationship between the number of students and the number of teachers in each school to be?
A: not enough information
B: negative correlation
C: no correlation
D: positive correlation
I am pretty sure that the thing which you expect the relationship between the number of students and the number of teachers in each school is positive correlation, because it is an example of relation in which both variables move in tandem.
