Primary Data is a type of data gotten from the main sources or first-hand sources. As the name implies, primary data is a type collected by researchers directly from real sources. At times, other research works are usually based on primary data. Primary data can be collected through various methods such as observations, interviews, experiments, Questionnaires, group discussions, etc. Primary data can be evaluated using factors. It must be a reliable report, it must be well-founded, it must have a definite source, and it must be clearly verified.
On the other hand, secondary data is a type of data that is collected by analyzing the ones that have previously been gathered. Whenever you are interpreting research data that has previously been gathered, what you are producing is secondary data. Unlike primary data, which takes too much time to gather, secondary data does not take too much time. Secondary data does not require more effort like primary data.
