Chi-square test is used only for categorical variables. The summary table should only include zero or positive integers. If the total frequency is under 20 and any cell has an expected frequency less than 5, the Chi-squared approximation might be incorrect. If there are at least 2 rows and...
The chi-square critical value (x) can be any number between zero and plus infinity. The chi-square calculator computes the probability that a chi-square statistic (Χ2) falls between 0 and the critical value. Suppose you randomly select a sample of 10 observations from a large population. ...

The chi-square distribution (also called the chi-squared distribution) is a special case of the gamma distribution; A chi square distribution with n degrees of freedom is equal to a gamma distribution with a = n / 2 and b = 0.5 (or β = 2). Let’s say you have a random sample ta...

Instructions: This calculator conducts a Chi-Square test for one population variance (\(\sigma^2\)). Please select the null and alternative hypotheses, type the hypothesized variance, the significance level, the sample variance, and the sample size, and the results of the Chi-Square test will...
This lesson describes when and how to conduct a chi-square test of independence. Key points are illustrated by a sample problem with solution.
