In education and in other areas of the social sciences, studies are carried out of the perception of a group of people about a certain phenomenon under study and it is necessary to use specialized techniques for the analysis of this perception. The purpose of this article is to present the technique of multidimensional scaling as an option for analyzing perceptions and exemplify the use of perceptual maps, product of this technique, in studies where you want to capture the perception of a group of teachers and people in general. To do this, it explains what this statistical technique consists of, and as an example, it is applied to a set of data that include two scales that measure the perception of 288 mathematics teachers, in terms of the degree of implementation of a study program. The main conclusion reached is that the statistical tool of multidimensional scaling is appropriate to analyze the perceptions and opinions of teachers, this due to the ease of expressing these perceptions in graphic representations that show different dimensions (Bord et al., 2018). Multiple linear regression on the two axes of the perceptual maps is recommended to improve its interpretation.
