The symbol of the chi-square test is "x 2 " (i.e., "x" raised to the power 2). "x 2 " is the summation of the (observed count-expected count) 2 /expected count. The formula of the chi-square goodness of fit test is given as follows: Where, "x 2 " is the chi-square statistic "O i " is the observed frequency "E i " is the expected frequency

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.

The χ2 test first calculates a χ2 statistic using the formula: where: Aij = actual frequency in the i-th row, j-th column Eij = expected frequency in the i-th row, j-th column r = number or rows c = number of columns A low value of χ2 is an indicator of independence.

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.
