统计分析的每一步都要求研究人员根据统计知识和自己的数据知识做出决策。对于新手分析师来说,这是认知上的要求,可能会导致错误和对结果的误解。我们提出Statsplorer,一个软件,可以帮助新手学习和执行推理统计测试。它允许用户从他们的研究问题开始数据分析。Statsplorer自动测试必要的统计假设,并使用可视化来指导用户选择统计测试和解释结果。我们比较了Statsplorer与统计讲座,并研究了Statsplorer如何在AB/BA交叉实验中为新手学习统计做准备。结果表明,在讲座之前使用Statsplorer会导致在理解统计假设和选择适当的统计检验方面的考试成绩显着提高。Statsplorer是开源的,可以在http://hci.rwth-aachen.de/statsplorer上在线获得。
Each step of statistical analysis requires researchers to make decisions based on both statistical knowledge and the knowledge of their own data. For novice analysts, this is cognitively demanding and can lead to mistakes and misinterpretations of the results. We present Statsplorer, a software that helps novices learn and perform inferential statistical tests. It lets the user kick-start data analysis from their research questions. Statsplorer automatically tests necessary statistical assumptions and uses visualizations to guide the user in both selecting statistical tests and interpreting the results. We compared Statsplorer with a statistics lecture and investigated how Statsplorer prepares novices for learning statistics in an AB/BA crossover experiment. The results indicates that using Statsplorer prior to the lecture leads to significantly better test scores in understanding statistical assumptions and choosing appropriate statistical tests. Statsplorer is open-source and is available online at: http://hci.rwth-aachen.de/statsplorer.
