Your SME has told you that the valid values for Student Status are Freshman, Sophomore, Junior, and Senior.
Which of the following is the smallest acceptable set of equivalence classes for Student Status?
- Graduate
- Honors, Sophomore
- Graduate, Freshman, Senior
- Honors, Freshman, Senior, 918
You Answered: A
Correct Answer: B
Since this data attribute references a set of values, it only requires one valid equivalence class (any member of the set) and one invalid equivalence class (anything that is not a member of a set). Option A does not provide a valid equivalence class. Options C and D are acceptable, but they specify more equivalence classes than required.
