Consequences of Test Score Use as Validity Evidence: Roles and Responsibilities

This article has three goals. The first goal is to clarify the role that the consequences of test score use play in validity judgments by reviewing the role that modern writers on validity have ascribed for consequences in supporting validity judgments. The second goal is to summarize current views on who is responsible for collecting evidence of test score use consequences by attempting to separate the responsibilities of the test developer and the test user. The last goal is to offer a framework that attempts to prescribe the conditions under which the responsibility for collecting evidence of consequences falls to the test developer or to the test user.     

A Study of the Relationship between the Diets and the Health of 25 Negro Families in Scotland Ville,Louisiana

Using a hypothetical data set, the authors provide concrete examples to illustrate that canonical correlation analysis is a general linear model, subsuming other parametric procedures as special cases. Specific statistical techniques included in the analysis are t tests, Pearson correlation, multiple regression, ANOVA, MANOVA, and discriminant analysis. The discussion is aided by an initial explanation of the logic of canonical analysis. Further, similarities between the canonical technique and other univariate and multivariate procedures are highlighted. The treatment is intended to reiterate a framework in which statistical concepts can be presented to students.

Drive for dough. PGA Tour golfers’ tee shot functional accuracy,distance and hole score

Abstract

A player’s ability to score low is critical to the tournament outcome in golf. The relationships of round scores to fairways hit in regulation or striking distance on two holes per round have been investigated before with some disagreement. The purpose is therefore to examine the relationships of par-4 and par-5 hole scores to tee shot functional accuracy and distance, measured as lie of the ball and penalty, and striking distance or distance to the pin for the second shot. Such information is possible to collect without interviewing players. The best US Professional Golfers’ Association Tour players’ statistics during a season are used, provided by the Professional Golfers’ Association Tour and ShotLink. Distance was measured with laser equipment. The results include significant (P < 0.05) correlations between score and striking distance or distance to pin, when hitting rough but not fairway on par-4s and when hitting fairway and rough on par-5s. It is therefore relevant, for performance, to consider the type of fairway miss as well as the striking distance in relation to the par and length of the hole. The findings can be considered when making gap and needs profiles, and when making tactical decisions for tee shots on different types of holes.     

2012伦敦奥运会中外女排接应二传运动员得分手段和效果的研究

采用录像观察、数理统计等方法,对2012伦敦奥运会中外女排接应二传基本情况、得分手段和效果进行分析,结果表明:中国女排接应二传平均年龄正处于竞技排球黄金阶段,身体形态、网上高度及绝对弹跳力方面中国女排接应二传均具有优势。发球上,中外女排接应二传得分均是采用跳飘及上手飘,但得分效果不及交手队;拦网上,得分均是来自拦前排强攻的球;扣球上,快攻是中国女排接应二传得分的主要手段,而交手队主要以前排强攻得分为主,中国女排接应二传的前排强攻得分效果与交手队相比,相对较差。

科技评价结果标准化方法及对组合评价的影响

为了充分利用科技评价中多属性评价方法的评价结果,本文首先分析了不同科技评价方法评价结果的特点,确定了科技评价结果标准化的原则和方法,提出了一种新的负值评价结果标准化方法——极差标准化方法,并以熵权法、TOPSIS、主成分分析三种评价方法为例,采用中国科学技术信息研究所农业学术期刊数据,分析了标准化方法不同对组合评价的影响。认为对于线性评价结果,一般情况下没有必要做标准化处理,对于非线性评价结果,定序评价方法不存在标准化问题,定值评价方法都要进行标准化。在进行组合评价时,所有的评价方法都要进行标准化处理,不同的标准化方法会影响组合评价结果。     

档案网站评价体系的研究与构建

档案网站评价体系的构建对于全面准确地分析和评价档案网站建设水平、规范和控制档案网站的建设发展、指导用户对档案网站的访问、改进和提高档案部门服务质量和效率具有重大意义。本文通过对档案网站评价体系结构的设计、对评价表的设计、对其中的评价指标和分值计算方法的详细说明,研究和构建了一个科学、全面、具有可操作性和导向性的档案评价体系。并通过一个档案网站评价实例具体说明了该评价体系的应用和计算方法,最后对档案网站评价的组织和实现进行了研究和说明。     

参加体育锻炼能提高居民社会交往能力吗？——基于倾向值得分匹配方法的检验

体育锻炼是促进居民社会交往的重要途径。基于中国综合社会调查2015（CGSS 2015）数据,采用OLS回归以及倾向值得分匹配法考查体育锻炼对居民社会交往的影响效应。研究结果发现,参加体育锻炼显著增加了居民社会交往的可能性,对居民社会交往的提升作用存在民族、婚姻、教育、健康水平以及代际差异。对于在城市和农村不同环境中长大并进行体育锻炼的居民,后者更注重社会交往。此外,参与体育锻炼对受教育程度高的个体在社会交往方面的提升作用更大。使用"倾向值得分匹配"方法重新检验后,这一结论仍然稳健。
