Ensino de probabilidade e estatística

Abstract

The main objective of this work is to explore strategies that make the teaching of Probability and Sta- tistics more accessible and engaging for students, through the use of practical examples and interactive activities. To achieve this goal, we begin by presenting fundamental concepts of probability theory and statistics, as well as the teaching methodologies associated with these subjects. The research was conducted at the Secondary School 25 de Novembro in Quissico, involving a population of 146 students from the 12th grade, of which a sample of 107 students was selected. The adopted methodology consisted of three stages: the first was the orientation for the pre-test, followed by the teaching of the lesson, and finally, the application of the post-test on the introduction to probability. For data processing, the statistical package R version 4.4.0 was used, along with the RStudio com- piler, with a confidence level of 95%. It was observed that after performing the normality test, the data did not show a normal distribution. Therefore, non-parametric tests were employed, such as the Wilcoxon test, to compare the two dependent samples, aiming to analyze the evolution of the results before and after teaching.
