Activity-4 Ques 4

Katheryn has recently read the booker prize winner “The Discomfort of Evening” by Marieke Lucas Rijneveld, and decided to rate this book on the Goodreads website. There she is asked to rate the book on a scale of 1 - 5. What kind of scale(s) of measurement is(are) being used here for rating?  

Here the ans given by you is interval. 

But while rating just like in ordinal scale we cannot comment anything about a definite interval between them. So why is it interval and not ordinal?

When we give ratings like Excellent, Good, or Bad, the scale is ordinal. They are nominal values that can be ordered but there is no way to check whether the difference between Bad and Good is the same as the difference between Good and Excellent. The rating in the question you are referring to is on a scale of 1 to 5. The ratings you can give are 1,2,3,4 and 5 and they have a difference of 1 between any two consecutive values. That is, the interval between the values is a fixed unit of measure, one. So this is interval scale of measurement.

Thank you for the clarity.
