   Question

   Suppose you are interested whether academic performance depends on how much time a student spends in the campus bar. Academic performance is measured using a student’s GPA. The time a student spends in the campus bar is measured in number of hours per week.

   What is the level of measurement of academic performance?

   
   
   1. FALSE: Nominal
   2. FALSE: Ordinal
   3. TRUE: Interval
   4. FALSE: Ratio
   
   

   Solution

   GPA is measured at the interval level. The difference in academic performance between 2.1 and 2.2 can be assumed to be the same as the difference between 3.4 and 3.5.

   
   
   1. The values are not just categories.
   2. The values do not just have order.
   3. Correct
   4. Does a GPA of 4 mean that academic performance is twice as high as a GPA of 2?
