Which primary and secondary data are collected for the definite purpose?

Primary data is collected directly from original sources through methods such as surveys, interviews, or experiments, tailored to address specific research questions. Secondary data involves the analysis of existing information gathered by others, such as academic articles, reports, or databases. Both types of data serve the definite purpose of providing insights and evidence to support decision-making or research objectives. The choice between primary and secondary data often depends on the research goals, available resources, and the required specificity of the information.
