A virtual experience to strengthen students' understanding of inference in experimental design

Although our students correctly define the terms p‐value, Type I and Type II errors, they sometimes misinterpret results from real data. In this work we present an assignment intended to clear up these misconceptions.     

Participatory practices in policy-making: Negotiating democratic outcomes or manoeuvring for compliance?

This article explores the nature of participatory practices in policy-making in basic education and their impact on the directions and outcomes of policy. Drawing on theoretical developments in policy studies, the focus is on non-formal education as a policy challenge for EFA. Data are presented from a recent field study undertaken in Uganda of the process to establish a policy framework for basic education for disadvantaged children. A multi-dimensional frame is used for the analysis of the practice of policy development. It is argued that NFE, because of its amorphous and marginal nature, is an important arena for contesting the orthodoxy of educational thinking, policies and practices. Yet the full engagement by all stakeholders by itself cannot guarantee a democratic outcome, as the nature of policy processes may allow for counter-actions that preserve the existing education hierarchy.     

一类污染数据回归模型参数的最大似然估计及若干不变性

摘要 本文研究一般的线性回归模型的观测向量受到一种污染时未知参数的最大似然估计,并讨论了若干用于统计推论的统计量在污染下的不变性。不变性的研究提示我们,在何种统计推断中可无视污染的影响。

Assessing math attitude through the Attitude Toward Mathematics Inventory – Short form in introductory statistics course students

Math attitude refers to emotional responses, beliefs, and behaviors towards mathematics. Several studies measured the relation with math learning and related variables, but very few with statistics learning. To better investigate this relation has become increasingly relevant to have a measure that ensuring multidimensionality and shortness. The aim of the present paper was to confirm the factor structure of the Lin and Huang (2014)'s ATMI - Short Form (ATMI - SF) when administered to Italian college students attending introductory statistics course, and to test its measurement invariance applying a multigroup confirmatory analysis. We also assessed the reliability and the incremental validity of the ATMI - SF by verifying whether it predicted statistics achievement over and above the effect of math knowledge. The overall findings provide that ATMI - SF is a reliable and valid measure to assess math attitude among college students who attend introductory statistics courses in non-mathematical courses.

研究问题与统计方法的有机配合

在实证性研究的设计阶段．研究者应明确研究课题，界定自变量、因变量、控制变量和协变量的操作定义和相互关系，并根据研究课题和变量关系选择合适的统计技术。分别讨论了分析变量关系、探讨组间差异、预测组别隶属以及考察变量结构这四类统计技术解答的研究问题，并通过科研实例介绍了根据研究问题选择统计技术的思路。特别指出。一个研究问题通常可以由多个统计方法加以解决。     

第27届奥运会金牌统计分析

主要以献资料法对第27届奥运会金牌进行了统计，结果表明：金牌分布具有下列特征：1．前三名金牌国所获金牌占金牌总数的32．9％。2．竞技实力特征：欧洲最强，其次是实力相当的亚洲和美洲，存次是大洋洲，最弱是非洲。3．项目特征：项目实力的分布不均匀，表现出明显的地域优势和劣势特征，但某一国家垄断某一项目金牌是极其困难的。4．性别特征：存在男女相当、男弱女强、男强女弱三种倾向。
