According to Julienne Brabet, statistics are limited to revealing links between data, but to truly grasp how a phenomenon works, it is necessary to formulate hypotheses and verify them by demonstrating that they explain the facts in a way that is consistent with a set of other hypotheses that have been validated in a given context. In other words, understanding a subject involves developing theories and testing them to ensure their validity in relation to reality.

Véronique Boulocher, Sabine Flambard, and Sylvie Jean emphasize that market analysis aims to enable a company to adapt to its changes, establish itself within the market, or make strategic marketing decisions. However, this analysis must be conducted with specific consideration for the company in question. Each analysis is therefore relative: what may be an opportunity for one company may be perceived as a threat by a competitor in the market, thus highlighting the importance of the individual perspective in any analytical approach.
