Primary Research
Primary research involves gathering data that has not been collected before. Methods to collect it can include interviews, surveys, observations or any type of research that you go out and collect yourself.
Secondary Research
Secondary research, also known as desk research, is a research method that involves compiling existing data sourced from a variety of channels. This includes internal sources (e.g.in-house research) or, more commonly, external sources (such as government statistics, organizational bodies, and the internet).
