Statistics - Chi Squared table - The numbers in the table represent the values of the ${chi^2}$ statistics. Areas of the shaded region (A) are the column indexes. You can also use the Chi-Square Distribution to compute critical and p values exactly.
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...
Chi Squared Table The chi squared table below is used in hypothesis testing. It helps you to decide whether to accept or reject the null hypothesis. The

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...

You could take your calculated chi-square valueandcompare it to a critical valuefroma chi-square table. If the chi-square valueismore than the critical value, then thereisa significant difference. 你也可以用p值。首先陈述原假设和替代假设。然后为结果生成卡方曲线和p值(参见:计算卡方p值Excel)。较...
The most straightforward problem is finding the right-tail critical value because the chi-square table displays that without further calculations. Right-tailed chi-squared tests are the most common type. Suppose you use a significance level of 0.05, and your chi-square test has 5 degrees of free...

Don’t want to use chi-squared for small expected table values, so do cross tab test: Cross tab test: Cannot have more than 20% of expected cells with values ≤ 5, and no cells can have value ≤ 3. If it fails the test, you can do three things: ...
