Primary research is when the researcher collects the data for his own purposes, according to Know This, a marketing research website. This data is original and collected for a specific purpose or to solve a specific problem. In contrast, secondary research is when someone other than the researcher has collected the data. Primary data may be qualitative, which is usually in the form of words, or quantitative, which is usually in the form of numbers.
Primary research costs more than secondary research since the data has to be collected.
The planning and execution of collecting primary data takes more time than just acquiring secondary data.
Not all primary research projects are feasible, and some are only feasible for those with the deepest pockets.
