Gunnar Ekbohm 《Psychometrika》1982,47(1):115-118
The problem of testing two correlated proportions with incomplete data is considered by means of Monte Carlo simulations studies. A test proposed in this paper, which can be regarded as a generalization of McNemar's test, is recommended in all cases with incomplete data and not too small samples. 相似文献

To date, virtually all techniques appropriate for ordinal data are based on the uniform probability distribution over the permutations. In this paper we introduce and examine an alternative probability model for the distribution of ordinal data. Preliminary to deriving the expectations of Spearman's rho and Kendall's tau under this model, we show how to compute certain conditional expectations of rho and tau under the uniform distribution. The alternative probability model is then applied to ordinal test theory, and the calculation of true scores and test reliability are discussed. 相似文献

对从HSK题库中计算机自动生成试卷稳定性的试验检验 总被引:1,自引:0,他引:1
由计算机从题库中自动生成的试卷能否保持难度的相对稳定?根据IRT进行的等值误差范围有多大?为了回答这些问题,本文以共同组等值作为标准,对基于IRT之上的共同题等值误差进行了试验检验。试验中,采取一定措施保证了考生的动机水平。结果显示,IRT等值的校正方向都是正确的。在4个分测验中有3个分测验的的等值校正效果较理想,1个分测验的等值校正效果不够理想。计算机自动生成的试卷与原有人工命制的试卷在得分方面比较一致,分数相关达到0.931,获得证书的情况也是比较一致的。 相似文献

Roberto Colom María ngeles Quiroga Manuel Juan-Espinosa 《Personality and individual differences》1999,27(6):9
Sex differences in cognitive abilities were determined using the norms from two standardizations of the Differential Aptitude Test (DAT) and the Primary Mental Abilities (PMA) conducted between 1979 and 1995 in Spain. The standardized sex differences (ds) were computed separately for the DAT and the PMA subscales. Males scored higher in the DAT subscales Verbal Reasoning, Numerical Ability, Spatial Relations and Mechanical Reasoning, as well as in the PMA subscales Numerical Ability and Mental Rotation. Females scored higher in Inductive Reasoning (PMA-R) in the 1979 and 1995 standardizations. Taken together, these data do not support the hypothesis that cognitive sex differences are disappearing: there are still some differences favoring females and still some differences favoring males. 相似文献

中国古代心理测验及其特色与价值 总被引:3,自引:0,他引:3
文章对中国古代心理测验历史进行反思,认为中国古代心理测验是以知人观为其理论依据,渊远流长,内容丰富,既有类似于现代西方的小时空心理测验,也有西方至今尚未充分关注的大时空心理测验。文章还阐释了中国古代心理测验的几个具体特色;置测验于生活实际中;文化与超文化测验井存;测验与选拨、训练、教学、娱乐相结合;精于定性,疏于定量。 相似文献

We provide a unified, theoretical basis on which measures of data reliability may be derived or evaluated, for both quantitative and qualitative data. This approach evaluates reliability as the proportional reduction in loss (PRL) that is attained in a sample by an optimal estimator. The resulting measure is between 0 and 1, linearly related to expected loss, and provides a direct way of contrasting the measured reliability in the sample with the least reliable and most reliable data-generating cases. The PRL measure is a generalization of many of the commonly-used reliability measures.We show how the quantitative measures from generalizability theory can be derived as PRL measures (including Cronbach's alpha and measures proposed by Winer). For categorical data, we develop a new measure for the general case in which each of N judges assigns a subject to one of K categories and show that it is equivalent to a measure proposed by Perreault and Leigh for the case where N is 2.Bruce Cooil is an Associate Professor of Statistics, and Roland T.

一般能力倾向成套测验简介及其中国试用常模的修订 总被引:5,自引:0,他引:5
本文对一般能力倾向成套测验作了简要的介绍。为了试用,对它进行了修订。版本是以日本劳动省1983年修订版为蓝本的。日本的版本是来自美国。为了适合国情,对该测验在三个方面作了微小的变动。修订工作自1989—1992年初。标准化样组是由全国17个中等以上城市初二至高三学生2148名构成的。男女学生的比例为1:1。该测验在结构效度上有很好的证据,稳定信度分数相当好。 相似文献

This paper reports a study of the relation between demographic variables and neuropsychological test performance in a sample of 141 normal subjects. A preliminary analysis demonstrated the importance of age, educational level, sex, and Verbal IQ for the prediction of neuropsychological test performance. The main study is a detailed analysis of the relation between these four variables and neuropsychological test performance. The results are presented in the form of standardized regression coefficients and are discussed in relation to the problem of predicting expected premorbid performance in neuropsychological tests. 相似文献

This note is concerned with differences and similarities between structural models for analyzing change, which are conceptualized within two different modelling traditions: the one based on the classical test theory, and that within the factor-analytic approach. It is shown that these two possibilities lead to models for studying change, which are indistinguishable when using for data analytic purposes structural modeling programs, such as LISREL, EQS, COSAN, LISCOMP, RAMONA, EzPATH, SAS PROC CALIS. The reason for this data-analytic equivalence of the two conceptually different types of models is the confounding of their differences in the corresponding implied covariance matrix structures. 相似文献
