Four rather different scatterplots of two variables X and Y are given, which, after dichotomizing X and Y, result in identical fourfold‐tables misleadingly showing no association. 相似文献

This paper discusses an innovative approach for using live data generated through student projects or through experiments using student subjects. This live data set, in which the students have a vested interest, becomes the foundation upon which the learning of the statistical concepts is built. 相似文献

We explain how to simulate both univariate and bivariate raw data sets having specified values for common summary statistics. The first example illustrates how to ‘construct’ a data set having prescribed values for the mean and the standard deviation – for a one‐sample t test with a specified outcome. The second shows how to create a bivariate data set with a specified correlation coefficient. 相似文献

Reasoning with data is already pervasive in society, and its importance as a life skill is increasing. We argue that the current statistics curriculum in the United Kingdom at the secondary level does not prepare our young people adequately, and suggest ways in which it could be improved. 相似文献

The notion of independence between two nominal variables is typically introduced through the use of chi‐square analysis of contingency tables, while the topic of prediction of one nominal variable from a second nominal variable using optimal prediction to the mode is often omitted. Through the use of a questionnaire, this article indicates that there is considerable confusion among students on the difference between the concepts of independence and prediction, and remedies are suggested. 相似文献

The Assessment Resource Tools for Improving Statistical Thinking (ARTIST) Web site was developed to provide high-quality assessment resources for faculty who teach statistics at the tertiary level but resources are also useful to statistics teachers at the secondary level. This article describes some of the numerous ARTIST resources and suggests ways teachers may use these assessment resources. 相似文献

应用大数据教学测评系统分析学生学习情况,提供个性化学习服务成为教育领域关注的热点。以广州市花都区七所试点学校的教师和学生为调研对象,采用问卷调查的方法对教师和学生应用大数据教学测评系统的现状进行了分析。数据结果显示,大数据测评系统在教学中得到一定程度的应用,但仍然处于浅层次,师生在应用过程中师生普遍对大数据教学测评系统持有肯定的态度。随后从理念先行、分类分层、协同发展、校企协同等四个方面提出大数据教学测评系统的应用策略,以期为推动区域个性化教学提供借鉴。 相似文献

Although researchers have documented that some data make larger contributions than others to predictions made with least squares models, it is relatively unknown that some data actually make no contribution to the predictions produced by these models. This article explores such noncontributory data. 相似文献
