A Survey of Reading Attitudes was administered to 431 intermediate grade students enrolled in three inner-city elementary schools which are part of the Columbus (Ohio) Public Schools. The Survey is a multidimensional instrument which provides measures for eight different dimensions of reading attitude. An ANOVA was performed on scores for each of the eight dimensions to identify developmental changes in reading attitude during the intermediate grades. The results of the ANOVA’s and post hoc comparisons indicated significant patterns of change for the following dimensions: Expressed Reading Difficulty, Reading as Direct Reinforcement, Silent vs Oral Reading, and Comics. In contrast, the Reading as Enjoyment, Alternative Learning Modes, and Reading Group dimensions failed to show appreciable developmental changes. 相似文献

搭配词统计分析方面的文献不乏对具体方法和计算公式的陈述,但是对于其统计原理的解释并不充分,具体包括如下一些重要问题:词汇统计研究中总体与样本的概念、搭配词统计分析的基本模式、词频分布与词语概率、词汇统计研究中的假设检验原理.本文综合相关文献中的理论、结合统计学理论,对现有文献进行总结和补充,为常用的搭配词统计分析原理构建一个简单明了的解释体系. 相似文献

The statistical simulation technique is a very powerful and simple technique for answering complicated probabilistic questions regarding random experiments. The principles on which this technique is based are the Laws of Large Numbers (LLN). These laws say that under fairly general conditions, as the sample size increases, the sample quantities converge, in an appropriate sense, to the corresponding population quantities. (For details regarding LLN, see [1]). Here we illustrate the technique by giving some examples. 相似文献

Identification of distinct units within a continuous flow of human action is fundamental to action processing. Such segmentation
may rest in part on statistical learning. In a series of four experiments, we examined what types of statistics people can
use to segment a continuous stream involving many brief, goal-directed action elements. The results of Experiment 1 showed no evidence for sensitivity to conditional probability, whereas Experiment 2 displayed learning based on joint probability. In Experiment 3, we demonstrated that additional exposure to the input failed to engender sensitivity to conditional probability. However,
the results of Experiment 4 showed that a subset of adults—namely, those more successful at identifying actions that had been seen more frequently than
comparison sequences—were also successful at learning conditional-probability statistics. These experiments help to clarify the mechanisms subserving processing
of intentional action, and they highlight important differences from, as well as similarities to, prior studies of statistical
learning in other domains, including language. 相似文献

The Beginning of Statistical Inference: Comparing two Data Sets 总被引：1，自引：0，他引：1
The development of school students' understanding of comparing two data sets is explored through responses of students in
individual interview settings. Eighty-eight students in grades 3 to 9 were presented with data sets in graphical form for
comparison. Student responses were analysed according to a developmental cycle which was repeated in two contexts: one where
the numbers of values in the data sets were the same and the other where they were different. Strategies observed within the
developmental cycles were visual, numerical, or a combination of the two. The correctness of outcomes associated with using
and combining these strategies varied depending upon the task and the developmental level of the response. Implications for
teachers, educational planners and researchers are discussed in relation to the beginning of statistical inference during
the school years.

随着计算机网络技术的飞速发展和intemet技术的广泛应用，电子商务在现代企业生存与发展中显示出越来越重要的作用。但是，由于电子商务交易的跨地域性和交易的隐蔽性，交易中具有相当的交易风险。所以，在交易中应充分运用统计分析的方法对买卖双方的信用等级进行评价，形成具体的量化指标，以规避交易风险，从而确保电子商务交易的顺利完成。 相似文献
