Which option describes using data that has already been gathered and is available?

• A. Gather data from all universities
• B. Conduct a survey of people
• C. Use data that has already been gathered and available
• D. Collect new experimental data

Answer: (C)

Using data that has already been gathered and is available is an example of secondary data analysis. This approach means reusing data collected by someone else to answer your question, rather than collecting new information yourself. It saves time and resources and can be effective when the existing data fit your research needs and are of good quality. However, you’ll want to check that the data align with your question, understand how they were collected, and be aware of any biases or gaps since you didn’t control the data collection process. The other approaches describe gathering new information or creating primary data through new surveys or experiments, which is why they don’t fit the idea of using data that’s already available.
