7. Four scales of measurement were introduced in this chapter, from simple classification on a nominal scale to the more informative measurements from a ratio scale. a. What additional information is obtained from measurements on an ordinal scale compared to measurements on a nominal scale? b. What additional information is obtained from measurements on an interval scale compared to measurements on an ordinal scale? c. What additional information is obtained from measurements on a ratio scale compared to measurements on an interval scale?

Expert Solution
Step 1

Levels of measurement:

Nominal: It categorizes the objects without any natural ordering.

Ordinal: It categorizes the objects with natural ordering.

Interval: It has ordered values with the additional property of equal distances or intervals.

Ratio: It has ordered values; equal distances between values and has an absolute zero.
