The Marketing Research Mix or the MR mix was made in 2004 and published in 2007 by Nigel Bradley. He’s a university professor of marketing at the University of Westminster in London. This type of research was designed as a framework to help researchers design or evaluate marketing research studies. Like the marketing mix, the marketing research mix also has four Ps. However, unlike the marketing mix, these elements are consecutive and belong to the most important phases that have to be observed. These four Ps are purpose, population, procedure, and publications.
