Regressão logística aplicada na relação entre o tempo de prova e rendimento de alunos de disciplinas relacionadas a estatística

Abstract

Can the time it takes a student to complete an assessment influence his / her performance? To answer this question, the logistic regression model was used and the computer system R was used as an aid tool for the programming of graphs and statistical calculations. Keywords: Logistic regression, time under evaluation, odds ratio. In its development, evaluation was considered as a way of quantifying the performance of a student reflecting his degree of knowledge in a given content. For this, we use records of the initial and final moments when developing an assessment. The records of time spent were obtained from five different undergraduate classes, with subjects taught by the same teacher, with the same theoretical content and at the same university. The results confirm statistically that each additional minute that the student remains taking the test, implies in greater chances of obtaining a good performance, as well as differences in performance between the feminine and masculine genders, although not statistically different, demonstrating that the feminine gender has greater chances of reaching the average of 6 points. The model also confirms, according to the odds ratios, that throughout the evaluations the students' performance decreases, having the best score in the first evaluation. Through the references consulted, we understand that the difference in the grades of each student is influenced by different factors, the result of their particular experiences.
