| chi-square test |
A chi-square test is any statistical hypothesis test in which the test statistic has a chi-square distribution if the null hypothesis is true. These include: * Pearson's chi-square test* Some likelihood-ratio tests are approximately chi-square tests when the sample-size is large. They are widely used in logistic regression. ...

| chi-square test |
A statistical significance test based on frequency of occurrence; it is applicable both to qualitative attributes and quantitative variables. Among its many uses, the most common are tests of hypothesized probabilities or probability distributions (goodness of fit), statistical dependence or independence (association), and common population (homogeneity). ...

| chi-square t. |
any statistical hypothesis test that employs the chi-square (χ2) distribution (q.v.), especially two tests applied to categorical data: the χ2-test of goodness of fit, which tests whether an observed frequency distribution fits a specified theoretical model, and the χ2-test of independence or homogeneity, which tests whether two or more series of frequencies (the rows and columns of a contingency table) are independent. In both cases the test statistic is the sum over all categories of the squared difference between the observed and expected frequencies divided by the expected frequency, under the null hypothesis. The sampling distribution of this χ2-statistic approaches the χ2-distribution as the sample size increases, under the null hypothesis.
