chi-squared test a statistical routine which is a test of SIGNIFICANCE, comparing the observed results of an experiment or sample against the numbers expected from a theory or prediction. The test produces a value called chi-squared (χ2) which is: The χ2 number is then converted to a ...
Chi-Square is a nonparametric test meaning we do not make any assumptions about the underlying distribution (i.e. a normal distribution). THREE DIFFERENT CHI SQUARE TESTS Chi Square Test for Goodness of Fit (GOF)-We compare our data to a “model”(many times these models have percentages an...

卡方检验属于非参数检验范畴，它不依赖于特定的参数或正态分布的假设，因此有时也被称作自由分布检验。这类检验主要应用于数据被分类的情形，例如区分民主党和共和党，这种分类涉及名义量表或顺序量表，通常无法计算平均数和方差。卡方检验分为两种主要形式：拟合度的卡方检验与卡方独立性检验。它们通过比较...
卡方检验（Chi-Squared Test）是一种用于分析两个分类变量间差异性或相关性的统计方法。其适用条件是，两个变量均为分类变量。例如，在妊娠期高血压与胎儿宫内生长受限之间的差异关系研究中，卡方检验可以评估两者之间的关联性。在SPSS中，进行卡方检验的步骤取决于数据的输入方式。如果数据以频数分布形式...
(Chi-Squared Test) 条件:X和Y都是分类变量 如:妊娠期高血压与胎儿宫内生长受限的差异关系 SPSS步骤根据数据分布选择 一、spss输入数据为频数分布,需要先加权再进行卡方检验操作 ² 第一列输入行(分组) 信息,其中0表示否,1表示是; ² 第二列输入列(关注的结局)信息,其中0表示否,1表示是; ...
