Use this Chi Square calculator to get a critical value for a Chi Squared distribution given a probability and degree of freedom.
Use the table below to find the chi-square critical value for your chi-square test or confidence interval or download the chi-square distribution table (PDF). The table provides the right-tail probabilities. If you need the left-tail probabilities, you’ll need to make a small additional calculation.
Use this Chi Square calculator to easily test contingency tables of categorical variables for independence or for a goodness-of-fit test. Can be used as a Chi-Square goodness-of-fit calculator, as a Chi-Square test of independence calculator or as a test of homogeneity.
This calculator will tell you the critical Chi-square (Χ2) value associated with a given (right-tail) probability level and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'.
You can use this chi-square calculator as part of a statistical analysis test to determine if there is a significant difference between observed and expected frequencies. To use the calculator, simply input the true and expected values (on separate lines) and click on the "Calculate" button to generate the results.
This is a easy chi-square calculator for a contingency table that has up to five rows and five columns (for alternative chi-square calculators, see the column to your right). The calculation takes three steps, allowing you to see how the chi-square statistic is calculated.
Chi Square Calculator is an online free tool used to find the chi-square value by using the chi-square statistics and performing the chi-square test to determine the relationship between the variables of the given data set by finding the values of the degrees of freedom and the p-value of the data.
The chi-square calculator computes the probability that a chi-square statistic (Χ 2) falls between 0 and the critical value. Suppose you randomly select a sample of 10 observations from a large population.
An online Chi-square calculator for large tables, from 2X2, 3X5, to 10X10 or more. The accurate Chi-square test p value is simply one step away!
Here you can quickly determine the critical value (s) for two-tailed tests, as well as for one-tailed tests. It works for most common distributions in statistical testing: the standard normal distribution N (0,1) (that is when you have a Z-score), t-Student, chi-square, and F-distribution.
