Detailed explanation-1: -Examples of nominal data include movie rating (G, PG, PG13, R, NC17), T‐shirt size (S, M L, XL), or your letter grade on a term paper. The difference between Nominal and Ordinal data is that Ordinal data can be ranked, while Nominal data are just labels.
Detailed explanation-2: -The standard survey rating scale is an interval scale. When you are asked to rate your satisfaction with a piece of software on a 7 point scale, from Dissatisfied to Satisfied, you are using an interval scale.
