Abstract: This study aims to analyze the influence of interpersonal communication skills on students’ science performances. Moreover, gender and high school background are also analyzed. This study uses a non-parametric bootstrap for regression models. It allows us to avoid statistical assumption tests which usually must be done in the traditional regression estimation. Both qualitative and quantitative methods are used in this study. As many as 72 undergraduate students are used. All statistical results are performed using R program. The empirical results reveal that interpersonal communication skills affect students’ science performance positively. The results also show gender and high school background have positive impact on science performance. Overall, the results reveal that bootstrap approach in regression produce better accuracy. This research implies the importance of interpersonal communication skills to be mastered by all students, so they can adapt properly during their education as well as graduating from school.
