What does primary research involve?

Primary research is defined as the process of collecting original data that has not been previously gathered or analyzed. This form of research directly involves the researcher engaging with subjects to obtain firsthand information, which can include conducting surveys and observations. By utilizing methods such as surveys, questionnaires, and direct observation, researchers gather data that is specific to their study's objectives. This makes the collected information unique and tailored to the particular research question at hand.

In contrast, reading existing literature pertains to secondary research, where researchers analyze data and conclusions that others have previously compiled. Analyzing historical data also aligns with secondary research, focusing on interpretations and trends derived from data that were collected previously. Conducting interviews from secondary sources indicates a reliance on information that has already been shared or documented, rather than original data collection. Thus, option B accurately encapsulates the essence of primary research.
