Primary and Secondary research are 2 Types of source research.
PRIMARY RESEARCH
In Primary research, there is no data available for you, so the you has to start from scratch. This means that your needs to design questionaires, collect data from people and then analyse the result.
Primary research is an original research method used to research information for a specific purpose in order to obtain knowledge on a subject.It is first hand, and it's information that you either already knew or information you found and put into your own words.
You can also use primary reesearch to create interviews, surveys & questionaires, in which you can ask quantitive & qualitive questions.
Quantitive questions are closed questions with multiple choice answers, yet answers are prewritten.
Qualitive questions are open questions, with no set answers, to get more quality out of peoples answers.
SECONDARY RESEARCH
If you are doing secondary research, you have the necessary data available. These data are made available through other publications or reports, like newspaper or annual reports of companies. If you are doing secondary research, there is no need to start from scratch, you just use the data or information done by other organizations or publications.
The important thing is that there are advantages and disadvantages for both methods.
