Primary data refers to information collected firsthand for a specific purpose or research. This data is original and is typically gathered through direct methods like surveys, interviews, observations, or experiments. Researchers or organizations collect primary data to address particular research questions or objectives that are not already answered by existing data. Since it is collected directly from the source, primary data tends to be more accurate and specific to the research goals. For example, a researcher conducting a study on student learning behaviors may use a questionnaire to gather primary data from students in various schools. Secondary data, on the other hand, is data that has been previously collected by someone else for a different purpose. This type of data is often obtained from sources such as government reports, academic studies, or organizational records. Researchers or organizations use secondary data to gain insights into a particular topic without having to collect new data themselves. It is often more convenient and cost-effective compared to primary data collection because the data is already available. However, since secondary data was collected for a different purpose, it may not always be directly applicable to the specific research question. An example of secondary data would be using census data
