The correct answer is D. Interpret primary data more insightfully.
Secondary data is data that has already been collected by someone else for a different purpose. It can be collected from a variety of sources, such as government reports, academic journals, and commercial databases. Secondary data can be used to identify a problem, test the hypothesis of the relevant present problem, and better define the problem. However, it cannot be used to interpret primary data more insightfully. This is because primary data is data that is collected specifically for the purpose of the current study. It is therefore more relevant and accurate than secondary data.
Here is a brief explanation of each option:
- Option A: Identify the problem. Secondary data can be used to identify a problem by providing information about the current state of affairs. For example, if you are interested in studying the problem of poverty, you could use secondary data to find out how many people live in poverty, what the causes of poverty are, and what programs have been implemented to address poverty.
- Option B: Test the hypothesis of the relevant present problem. Secondary data can be used to test the hypothesis of the relevant present problem by providing information about the relationship between variables. For example, if you hypothesize that there is a relationship between poverty and crime, you could use secondary data to find out if there is a correlation between poverty rates and crime rates.
- Option C: Better define the problem. Secondary data can be used to better define the problem by providing information about the context of the problem. For example, if you are interested in studying the problem of school dropouts, you could use secondary data to find out what factors are associated with school dropouts, such as family income, parental education, and neighborhood characteristics.
- Option D: Interpret primary data more insightfully. Secondary data cannot be used to interpret primary data more insightfully. This is because primary data is data that is collected specifically for the purpose of the current study. It is therefore more relevant and accurate than secondary data.
