Análisis clúster de las notas del alumnado de las pruebas de la EBAU en Santa Cruz de Tenerife

Abstract

The present article analyzes the evolution of the grades of students who took the EBAU exams (Baccalaureate Assessment for University Access) in the province of Santa Cruz de Tenerife over four academic years (2017-2018, 2018-2019, 2019-2020, and 2020-2021). In total, the database consists of more than 20,000 subjects. To this end, the grades of two subjects common to all students (Spanish Language and Literature II and English II), as well as a subject from the Scientific-Technological Baccalaureate (Mathematics II) and another from the Social Sciences and Humanities Baccalaureate (Applied Mathematics for Social Sciences II), were analyzed. For the analysis, a Two-Step Cluster Analysis was first carried out using the variables of the obtained grade, ownership of the educational center, and sex of the student for each subject. It was observed that the same three clusters were formed in all subjects: male students from public schools, female students from public schools, and students from private schools, both subsidized and unsubsidized. This indicates that there are significant profiles that influence access to the University.
