Twitter is a social network, widely used worldwide, characterized by providing information in real time, allowing interaction between people in relation to a particular topic. The objective of this research was to evaluate the use of Twitter at the level of South America in the areas of education, marketing, and politics, in the last five years. The statistical techniques used for the information process were Biplot, cluster, and comparative analysis, using the General Linear Model (GLM technique). As a result, it is noted that the South American countries that use Twitter most in the mentioned areas are Argentina, Brazil, and Chile. Twitter has multiple applications of great use in the scientific area for rapid decision making, minimizing costs, and maximizing the probability of success in a given objective.
