The chi-square (Χ2) distribution table is a reference table that lists chi-square critical values. A chi-square critical value is a threshold for statistical significance for certain hypothesis tests and defines confidence intervals for certain parameters. Chi-square critical values are calculated from chi-square distributions.

CHISQ.TEST(R1, R2) = CHISQ.DIST (x, df) where x is calculated from R1 and R2 as in Definition 2 of Goodness of Fit and df = (row count - 1) (column count - 1). The ranges R1 and R2 must have the same size and shape and can only contain numeric values. For versions of Excel prior to Excel 2010, the CHISQ.TEST function doesn't exist.

The chi-square goodness of fit test can be used to test the hypothesis that data comes from a normal hypothesis. In particular, we can use Theorem 2 of Goodness of Fit, to test the null hypothesis:. H 0: data are sampled from a normal distribution.. Example 1: 90 people were put on a weight gain program.The following frequency table shows the weight gain (in kilograms).

First, XLSTAT displays the results associated to the Chi-square test. The p-value (0.033) is lower than the significance level of 0.05. Thus, we reject the null hypothesis that maggot presence and banana variety are independent, with a 3.3% risk of being wrong. Next, Fisher's exact test results are displayed.
