23 maj 2022 · Calculate the chi-square value from your observed and expected frequencies using the chi-square formula. Find the critical chi-square value in a chi-square critical value table or using statistical software.
31 maj 2022 · 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.

29 sie 2023 · The Chi-square test is a statistical method used to determine if there's a significant association between two categorical variables in a sample.
In probability theory and statistics, the chi-squared distribution (also chi-square or -distribution) with degrees of freedom is the distribution of a sum of the squares of independent standard normal random variables.
6 sty 2020 · What is the Chi-Square Distribution Table? The Chi-Square distribution table is a table that shows the critical values of the Chi-Square distribution. To use the Chi-Square distribution table, you only need to know two values: The degrees of freedom for the Chi-Square test; The alpha level for the test (common choices are 0.01, 0.05, and 0.10)
This chi-square table provides the critical values for chi-square (χ 2) hypothesis tests. The column and row intersections are the right-tail critical values for a given probability and degrees of freedom. Typically, use your significance level to choose the column.
