Question

Quizplus · Accepted Answer

Secondary data refers to information that has been collected by someone else, such as government agencies, market research firms, or trade associations. This data can be accessed quickly and inexpensively, making it a convenient source of background information for businesses and researchers. Primary data, on the other hand, is collected specifically for a particular research project, and can be more time-consuming and expensive to obtain. Virtual data and observational data are not well-defined categories of data in this context, and are less commonly used terms. Therefore, option C is the best choice for this question.
