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 ...
The chi-squared test is such a hypothesis test. First, one selects ap-value, a measure of how likely the sample results are to fall in a predicted range, assuming the null hypothesis is true; the smaller thep-value, the less likely the sample results are to fall in a predicted range....

皮尔逊χ²检验(Pearson's Chi-squared Test),也称为卡方检验,是由英国统计学家卡尔·皮尔逊(Karl Pearson)在19世纪末提出的。它是统计学中最常用的一种非参数检验方法,最初设计用于评估观察频数与期望频数之间是否存在显著差异,常用于推断分类变量间的独立性或拟合优度检验。
