Amostragem

Authors: Vieira, Maria Teresa Ferreira de Amorim da Silva;
Abstract

Na presente dissertação apresenta-se um estudo dos métodos de amostragem mais utilizados na recolha de dados estatísticos. Far-se-á uma descrição, com exemplificação, de cada um deles explorando temas directamente relacionados com a problemática da amostragem como, por exemplo, a estimação de parâmetros, o dimensionamento da amostra e a realização de inquéritos. Por último, será apresentado um exemplo real de aplicação descrevendo um processo de sondagem levado a cabo em Abril passado com o objectivo de analisar o papel da disciplina de Matemática A no percurso escolar dos alunos das escolas secundárias do Concelho de Vila Nova de Gaia. Concretamente, investiga-se se o insucesso na disciplina de Matemática A, no 10ºano, interfere nas escolhas de progressão de estudos e até que ponto influencia a escolha de outra oferta educativa e formativa em que a disciplina de Componente de Formação Específica, Científica ou Tecnológica deixe de ser Matemática A para passar a ser outra opção que não Matemática A. ABSTRACT: In this dissertation are discussed sampling procedures most frequently used on statistical data collections. Examples and calculation of the sample size for each sampling procedure is also included. In the last chapter, a real example of application - a survey sampling- is presented. This survey sampling was executed in April. The main goal is the analysis of the role of the discipline of Mathematics A in the educational course of the students of secondary schools of Vila Nova de Gaia. The survey results are analyzed using classical statistical procedures. The dissertation is concluded with a brief summary of the survey results.
