How a Dummy Replaces a Student's Test and Gets an F (Or,How Regression Substitutes for t tests and ANOVA)

Using dummy variables, this note offers a convenient illustration to demonstrate that regression can replace both the one‐factor analysis of variance and the two‐population t test with independent random samples. The exercise also helps to develop students’ intuition regarding regression coefficients.     

Illustrating Regression Concepts

Modern microcomputers offer attractive possibilities to illustrate various concepts related to regression. In this article we describe how this can be achieved.     

Mad Libs Statistics: A 'Happy' Activity

This article describes a fun activity that can be used to help students make links between statistical analyses and their real-world implications. Although an illustrative example is provided using analysis of variance, the activity may be adapted for use with other statistical techniques.     

Intuitive Analysis of Variance – A Formative Assessment Approach

This article describes an assessment activity that can show students how much they intuitively understand about statistics, but also alert them to common misunderstandings. How the activity can be used formatively to help improve students' conceptual understanding of analysis of variance is discussed.     

A VBA‐based Simulation for Teaching Simple Linear Regression

In spite of the name, simple linear regression presents a number of conceptual difficulties, particularly for introductory students. This article describes a simulation tool that provides a hands‐on method for illuminating the relationship between parameters and sample statistics.

集体土地流转中集体角色的错位与回归

推进集体土地流转,加强农民集体权益保护需要其代表——集体找准角色定位,发挥积极作用。然而,在实际土地流转中,集体背离了其整体利益代表的角色定位要求,扮演了土地流转个人利益最大化的强夺者和乡（镇）政府以及办事处利益顺从者的角色,严重的角色错位侵害了本集体其他农民的合法权益。切实推进集体土地流转、加强农民权益保护,应从乡（镇）政府、农民、集体自身三方面入手摆正集体角色,切实保护农民的权益。     

回归教育之本--关于加强和改进教育工作的几点思考

教育是基础性、全局性、先导性的崇高的社会公益事业,是社会发展之本。促进学生素质的主动和谐发展,让学会学会做人、学会学习、学会创造与实践,这是教育工作之本。回归教育之本,就要革新教育理念,构建新的教育行为模式,改善教育制度环境,提高教师自身素质。

An open task to promote students to create statistical concepts through modelling

This article reports on the solutions of a group of 22 students, aged 15/16 years old, when facing a statistical modelling activity. They were given the salary lists of 5 companies and were asked what could be said about their salary structure; no hint was given. The results show that students not only used a wide range of data concepts and procedures but also developed their own criteria to measure dispersion.     

A Multiple Regression Project

The number of calories in a serving of a food item may be determined from the amount of fat, protein, and carbohydrates it contains. Students can uncover this relationship by collecting food data and then performing a multiple regression.

山东省农村居民消费函数模型结构分析

消费函数模型是表现消费者行为的重要方式,也是研究国民收入、消费支出、积累等宏观经济变量之间相互关系的有效手段.然而消费函数模型理论众多,应根据本国和本地的实际情况,采取合理的消费函数模型.本文利用最小二乘法估计出在消费函数理论假设条件下四种山东省农村居民的消费函数模型,并对其进行分析和比较.找出了一种比较适合我省农村居民的消费函数模型.     

Hold my calls: an activity for introducing the statistical process

Working with practicing teachers, this article demonstrates, through the facilitation of a statistical activity, how to introduce and investigate the unique qualities of the statistical process including: formulate a question, collect data, analyze data, and interpret data.
