Primary information, primary information, primary information, primary information

Your question is a bit vague. General market research is divided into the collection of first-hand data and the analysis of second-hand data, and the so-called collection of first-hand data is "desk research" in the traditional sense.

The analysis of secondary data refers to the data collected through real research. Market research generally has the following methods: 1. Questionnaire survey; 2. Interviews and focus groups; 3. Brainstorming; 4. Investigation; 5. Network survey; 6. Email and letter investigation; 7. Expert interviews (Delphi method) and other methods.

Doing research is generally better than first-hand information than second-hand information, because you must be different from others, second-hand information is often processed by others, the value is not as high as one hand, and one hand needs to be processed by oneself, so the things made will be different from others. Second-hand materials are generally integrated into other people's opinions, with personal subjectivity, and have lost their original appearance. First-hand information is like a mineral waiting to be mined.

The information should pay attention to the truth or falsehood, but in the truth or not, it is difficult to say who is true and who is false, some first-hand information is fake, after the research of others will be corrected, then the value of the first-hand information is not as high as the value of the data after the research. The opposite is also true. But it's still the same sentence, do research and do learning or you have to practice yourself to distinguish the authenticity, so that there is originality and value, that's it, you probably know the difference.
