PISA 2018 - Sample of Spanish student data

Dataset for manuscript "A comprehensive framework for explainable cluster analysis". This dataset contains student data collected for the OECD’s Programme for International Student Assessment (PISA). Specifically, we use a sample of 5,000 students randomly selected from the 35,943 Spanish students who took the PISA 2018 survey [1]. A total of 80 variables are selected. The dataset contains two files: - A CSV file containing the student data to which an additional column, `stu_original_order` has been added as unique identifier. - An Excel file containing a description of all variables.
