This calculator performs a two-tailed chi-square test and assumes a P value significance threshold of 0.05. The results page also includes the chi-squared statistic and its degrees of freedom. Notice the categor
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 2 columns, the null hypothesis (H0) is that the row...
Chi-square distribution calculator computes cumulative probability. Fast, easy, accurate. An online statistical table. Includes sample problems and solutions.
Note: The chi square table doesn’t offer exact values for every single possibility. If you use a calculator, you can get an exact value. The exact p value is 0.9265. Step 2: Use the p-value you found in Step 1. Decide whether to support or reject the null hypothesis. In general,...

To find the probability for a chi-square test statistic with degrees of freedom equal to df, use a chi-square distribution table or a statistical software. (The sample problem at the end of this lesson uses Stat Trek's Chi-Square Distribution Calculator to find the P-value for a chi-...
Knowing the value of chi-square and the number of degrees of freedom, you can compute a P value using this GraphPad QuickCalc web calculator, an Excel formula, or a statistical table. The P value answers this question: If all the assumpti...
