• A. Primary data
• B. Secondary data
• C. Qualitative data
• D. Explanatory variable

Answer: (A)

Data collected by the person who will use it is called primary data. This means you gather the information yourself for your specific study, so you know exactly how and why it was collected. Data that someone else collected for a different purpose and that you use is secondary data. Qualitative data describes non-numeric qualities or categories, not the source of the data, and an explanatory variable is a variable used to explain changes in another variable, not about who collected the data.
