Dataset of UNLam + e-status study

The dataset includes the data obtained for the randomized controlled study conducted from September to October 2018 in Universidad Nacional de La Matanza, Buenos Aires, with the aim to confirm efficacy of the web-based platform e-status in Probability and Statistics courses. Results appear in the manuscript <strong>Measuring the effectiveness of </strong> <strong>online problem solving </strong> <strong> for improving academic performance in a probability course</strong>, from the same authors. Hopefully published in the coming months. Students data have been anonymised, by removing ID numbers. Moreover, gender of students has been deleted, and age categorized into one of three classes (until 22 years, between 23 and 25, more than 25).本数据集包含2018年9月至10月在布宜诺斯艾利斯拉马坦萨国立大学（Universidad Nacional de La Matanza）开展的随机对照研究所获取的数据，研究目标为验证基于网页的e-status平台在概率论与统计学课程中的应用效能。相关研究成果已撰写为稿件《探究在线解题对提升概率论课程学业表现的有效性（Measuring the Effectiveness of Online Problem Solving for Improving Academic Performance in a Probability Course）》，作者为同一团队，该稿件有望于未来数月内正式刊发。学生数据已通过移除ID编号完成匿名化处理；此外，已删除学生的性别信息，并将年龄划分为三个组别：22岁及以下、23至25岁、25岁以上。
