Market research or Marketing research, are they the same, which one is better to use ? and why do you think so?

Marketing research and market research are both different from each other. Marketing research deals with secondary or primary research that helps to promote the company or the product. But market research helps to benchmark the firm or the product with respect to its competitors, it helps to know the possibilities of growth for the company.

Market research and Marketing research both are different we can't call them the same. In marketing research some how the researchers are keenly interest to study the demand and supply approach of customers and have specific target,for that they can use,either quantitative (surveys) or qualitative(Focus,In-depth- interviews,ethnographic and mixed research method etc).

While market research are more about the researcher collecting information over consumers preferences.

I think there is no better or worse in both, it's depend what do you really want,as a researcher to find out? If you simply like to understand just demand supply,mostly the researcher are conducting marketing research with the same research methods either it would be i.e. Quan or Qual. while market research are mostly the activity of collecting information on consumers trend and preferences. If you said which research method are good,rather marketing and market,it would be more convenient,I would have answer Qual, because in Qual our approach are more descriptive for a identifying a problem.
