Abstract(s)
As dificuldades no entendimento de conteúdos relacionados com a regressão linear e sua aplicação na resolução de problemas do dia a dia em Angola motivaram a realização do presente trabalho. Este, apresenta uma abordagem sobre os diversos aspetos da teoria de regressão linear e sua aplicação na área do ensino. O trabalho começa com uma abordagem introdutória sobre esta metodologia estatística e a problemática do rendimento académico a matemática dos alunos do ensino secundário em Angola. Nos capítulos 2, 3 e 4 apresentam-se os aspetos teóricos essenciais dos modelos de regressão linear simples e múltipla. No capítulo 5 apresenta- -se um estudo prático que poderá auxiliar as autoridades educativas da província do Moxico em Angola, e não só, a justificar as notas dos alunos do ensino secundário à disciplina de matemática. O modelo obtido através deste estudo, distingue as notas a língua portuguesa e a física, a idade e a renda familiar média, como alguns dos fatores que influenciam as notas dos alunos a esta disciplina. Finalmente, apresenta-se uma síntese dos principais resultados obtidos no trabalho e aspetos a ter em conta na realização de futuros trabalhos ligados ao tema.
The present work was motivated by the difficulties in understanding linear regression analysis and its applications in solving daily life problems in Angola. The work includes a discussion of several aspects of linear regression theory and its applications on the teaching area. The work starts with an introduction to this statistical methodology. The chapters 2, 3 and 4 present the essential theoretical aspects of simple and multiple linear regression models. Chapter 5 presents a real study about the academic performance of students from Moxico province of Angola. It was obtained a multiple linear regression model that will help the education authorities to explain student performance in mathematics. This model distinguishes the classification in Portuguese language and physics, the age and the family budget as some factors that take significant influence in the students performance in math. Finally, we present a summary of the main results and recommended the aspects to be taken into account in future works related to this subject.
