What would be considered ordinal

Question

I need to know what these variables would be classified as. Nominal, Ordinal, Interval and Ratio

 

The individuals are undergraduate students at the University of Wisconsin. The variables are sex, high school percentile, Cumulative GPA, Age, Total earned credits, Classification, School/College, Primary Major, Residency, Admission Type, ACT English Score, ACT Math Score, ACT Composite score.

Answer 1

Hey Bill,

Nominal describes just the NAME of something without a scale. A good example would be a pass/fail class.

That eliminates sex, classification, school/college, major, residency, and admission type because those are all names not on a scale.

ACT scores, however, are on a scale! So you can get a number from 0 to 36. This makes them ordinal.

High school GPA, percentile, and total earned credits also follow a system that is ordered. Ordinal = there is some system for ordering the numbers.

Hope that helps!
