P value: Rows X Columns: Chi-Square Test Introduction 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...
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 category names are not involved at all in the interpretation. Seethis examplefor help with...
