Biplot analysis for marking the quality of schools which compatible with national examination score

Abstract

The issue of national examinations has always been a matter of debate, because the scores are only used to determine the passing scores of students without follow-up. This study aims to map the quality of schools in accordance with national exam scores, and describe the relationship between national exam scores and influential variables. Data were taken from 22 high schools in Malang and Malang regencies with a population of 5396 people and a sample of 359 people. Data were analysed with a biplot package based on Mathematica programming, by combining scores and national deviation examination standards. Mapping the quality of schools is compatible with the national exam scores. It is obtained by the biplot with standard variables. The results obtained show that there is the compatibility of the rankings, and there is a significant positive correlation between all schools.
