Chi-square, a non-parametric test of significance, is an appropriate test when the data are in the form of frequency counts occurring in two or more mutually exclusive categories (nominal variables). It enables us to decide on the basis of sample if (1) a given set of counts (or ...
The Chi-Square Test of Significancedoi:10.1007/978-3-642-96732-0_11We 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...B. Roy Frieden...

Suppose you use a significance level of 0.05, and your chi-square test has 5 degrees of freedom. The truncated chi-square table below shows the critical χ2value. The table indicates that the critical value is 11.070. If the χ2test statistic is greater than or equal to 11.070, our resul...
