chi-square test n. A test that uses the chi-square statistic to test the fit between a theoretical frequency distribution and a frequency distribution of observed data for which each observation may fall into one of several classes. American Heritage® Dictionary of the English Language, Fifth ...
We previously noted the widespread occurrence in nature of the chi-square probability law . It was also found to describe the random behavior of the sample variance. Here we shall show how the chi-square law may be used to describe the state of "significance" of a set of data....

p-value大于0.05,因此我们可接受null hypothesis H0,即两个群组的均值统计相等。 (七) 卡方检验法(chi-square test,拟合优度检验) 通过前面两章的学习,我们知道可以采用t检验比较两个样本均数的差别是否有统计学意义,可以采用F检验多个样本均数之间的差别是否有统计学意义。在医学研究中,还常需对比两组或多组定性...

Chi-Square Test: Used for categorical data to assess whether there is an association between two variables. Regression Analysis: Used to explore the relationship between a dependent variable and one or more independent variables. It helps predict outcomes and assess the strength of relationships. Make...
