A group of women tried five brands of fingernail polish and ranked them according to preference. What level of measurement is this?

Nominal

Ordinal

Interval

Ratio

Answer: Ordinal

Step-by-step explanation:

We know that the ordinal scale is a level of measurement which is used when we are ordering attributes according to their ranks or preferences.

For example : In an exam we arrange position of students as:

First > Second > Third and so on.

Given : A group of women tried five brands of fingernail polish and ranked them according to preference. It means she is arranging the brands in an order.

Thus this is an ordinal level of measurement.
