International Students' Assessment Marks for First Year Economics and Statistics Units Collected over Four Semesters (2012-2013)

The data set includes assessment marks of undergraduate international students from a private tertiary education provider in Australia. Two first year units Business Economics and Business Statistics were included over a two-year period (2012-2013). There were three main assessments that students had to complete in each semester: (a) two short multiple choice tests (Test 1 and Test 2); (b) mid-semester test (MST) and; (c) final exam (FE). The two short multiple choice tests included an individual test and a group test. T-tests, paired t-tests and regression analysis were used to ascertain if group work improves student outcomes. In particular, the marks for the individual tests are compared to the marks for the group tests.

本数据集收录了澳大利亚某私立高等教育机构的本科国际学生的课程考核成绩。研究时段为2012至2013年的两年周期，包含两门大一课程：商务经济学（Business Economics）与商务统计学（Business Statistics）。每学期学生需完成三项核心考核任务：(a) 两场简短选择题测试（测试1与测试2）；(b) 期中测试（MST）；以及(c) 期末考试（FE）。上述两场简短选择题测试分为个人测试与小组测试两种形式。本研究采用T检验（T-tests）、配对t检验（paired t-tests）与回归分析（regression analysis），以验证小组作业是否能够提升学生的学业表现。其中，特别针对个人测试成绩与小组测试成绩展开了对比分析。
