Hello Yash,

Yes, you are correct. In the case of ordinal scale of measurement, the difference between two consecutive pairs of values need not be the same whereas in the case of interval scale of measurement, the difference between two consecutive values is a fixed unit of measure.

The possible ratings here are integers from 1 to 5. The ordered values 1, 2, 3, 4, 5 have a difference of 1 between any two consecutive values. Therefore, it has an interval scale of measurement. If the options for ratings were Good, Average, and Bad, then it has an ordinal scale of measurement since we do not know for sure that the difference between Good and Average is same as the difference between Average and Bad.

Hope this will help.

Thanks and regards
