In a survey undertaken by a university to gauge student satisfaction in its online MBA program, one question asked students to indicate their employment status (unemployed, employed part-time, employed full-time) Which of the following is true? A. This variable is quantitative. B. This is an identifier variable. C. This variable is categorical. D. This variable is both categorical and an identifier variable.

C. This variable is categorical

Explanation:

A categorical or discrete variable is one that has two or more categories (values).  There are two types of categorical variable, nominal and ordinal.  

A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories.

An ordinal variable has a clear ordering. For example, temperature as a variable with three orderly categories (low, medium and high).

Hence, the variables used in this scenario is an ordinal variable because it has a clear ordering.
