Experimentation, a common method of experimental sciences and technologies, consists of the study of a phenomenon, reproduced in the particular conditions of study of interest, generally in a laboratory, eliminating or introducing those variables that may influence it. Usually, the goal of experimentation is to prove or disprove hypotheses.


Variable is understood as everything that has its own distinctive characteristics and that is susceptible to change or modification. Science measures a dependent variable, an effect, and must explain it by virtue of independent variables, causes. For this, in the experimentation, the independent variables are modified and the change in the dependent variables is measured. [1]

Longitudinal studies

A longitudinal study with a panel, which is a group of people representative of the habitat and of adequate sample size, to whom a questionnaire is applied in continuous periods of time, is an experiment controlled by the variables that are studied: changes in the purchasing habits, evolution of human values, influences of social change, impact of information, etc. Yes, it would be to apply these theories to current social facts, but even to past facts, which in his perception can be modified by historians, handling other sources and with the change of his own personal imagination. For example, "the black legend of the inquisition" should be rewritten and "changed", just as the discourse of current history is experienceable: the changes in a community to which new requirements are being introduced with new characters, for example, and observing a concomitant social fact, etc.[citation needed]
