DA0-002 Data Concepts and Environments Practice Question
A data analyst is creating a report for a marketing campaign. The campaign data includes customer names, email addresses, and purchase history. Which of the following best describes the 'customer name' data type?
⚠ Common exam trap
CompTIA often tests the distinction between nominal and ordinal data by presenting a label that could be mistaken for having an order (e.g., 'customer name' might be confused with 'rank' or 'tier'), but the trap here is that names are purely categorical with no intrinsic ranking.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Nominal
Customer names are categorical labels that identify individuals without any inherent order or numerical value. This fits the definition of nominal data, which is used for naming or classifying variables. In data analysis, nominal data can be stored as strings and used for grouping or filtering, but arithmetic operations are meaningless.
