DA0-002 Data Concepts and Environments Practice Question
A market researcher conducts a survey with questions like "What is your favorite brand?" and "How many units do you purchase per year?" Which data types correspond?
⚠ Common exam trap
Many exam-takers confuse the order of the data types in the question, assuming the first listed data type must be quantitative, leading them to select Option B instead of correctly identifying 'favorite brand' as qualitative.

Qualitative & Quantitative
