二项分布检验(binomial test) 是对二分类变量的拟合优度检验,旨在考察每个类别中的观察值的频数与特定二项分布下的预期频数间是否存在统计学差异。本文实例演示在SPSS软件中实现二项分布检验的操作过程。 关键词:SPSS; 二项分布检验; 二项分布; 卡方拟合优度检验; 单样本卡方检验 二项分布检验和卡方拟合优度检验...
如果随机变量X为1的概率设为P,则随机变量X值为0的概率Q便等于1-P,形成二项分布。 SPSS的二项分布检验(Binomial test)正是要通过样本数据检验样本来自的总体是否服从指定的概率为P的二项分布,其原假设是:样本来自的总体与指定的二项分布无...
3. Run SPSS Binomial TestWe'd like to test whether the proportion of female spiders differs from .75 (our test proportion). Now SPSS Binomial Test has a very odd feature: the test proportion we enter applies to the category that's first encountered in the data. So the hypothesis that's...
SPSS Tutorial 3—Binomial Tests (Sign Test) in SPSS November 16, 2000 While studying for his statistics midterm, a UW student notices that his understanding of the concepts increases while he listens to Limp Biskit. He wonders if other students would also benefit by listening to Limp Biskit ...
accomplished (among other ways that you will discover later) with the BINOMIAL TEST (also known as the sign test) in SPSS. Below I’ve constructed a boxplot of the data in SPSS so that you can see how scores for the two conditions are distributed. (If you wanted to do this, you ...

Binomial testThe Binomial test procedure compares the observed frequencies of the two categories of a dichotomous variable to the frequencies that are expected under a binomial distribution with a specified probability parameter. By default, the probability parameter for both groups is 0.5. To change ...
此功能需要IBM® SPSS® StatisticsBase Edition。 檢定力分析在學習計劃、設計和傳導中扮演關鍵角色。 通常在收集任何取樣資料之前計算檢定力,但小型試驗性研究除外。 檢定力的精確估算可告知調查員,將基於真實替代假設下的有限樣本大小偵測統計顯著性差異的可能性。 如果檢定力過小,那麼偵測顯著性差異的可能性較小...
