Performance analysis of engineering students in statistics assessments / Siti Balqis Mahlan ... [et al.]

This study examines the performance of civil engineering students in probability and inferential statistics topics through two distinct assessment types: Assessment 1 (Quiz Individual) and Assessment 2 (Group Assignment). The Assessment 1 (Quiz Individual) focuses on probability topics such as binomial, Poisson, normal distributions, and sampling distributions, while the Assessment 2 (Group Assignment) evaluates their understanding of estimation, confidence intervals and hypothesis testing, including analyses of one mean, two means, one variance, and two variances. Additionally, a t-test for two means is conducted to determine if there is a significant difference between the mean scores of quizzes and assignments. The data includes scores from 26 civil engineering students, representing a subset of the total 346 engineering students across civil, chemical, mechanical, and electrical disciplines. The findings highlight key differences in individual and group performance, shedding light on common challenges faced by students in understanding statistical concepts and implications for improving teaching strategies.
