Types of chi-squared test There are two main types of the chi-squared test: A chi-squared goodness of fit test, which is used to test whether the observed frequencies (number of observations in each ...

A chi-square (also called chi-squared) test is a classical statistics technique that can be used to determine if observed-count data matches expected-count data. For example, suppose you have three ...

All the two-way test statistics described in this section test the null hypothesis of no association between the row variable and the column variable. When the sample size n is large, these test ...

In many biological problems, the experimenter may prefer to use a chi-square test for linear trends in proportions rather than the standard chi-square test of homogeneity. In this paper the ...
