The Excel CHITEST function uses the chi-square test to calculate the probability that the differences between two supplied data sets (of observed and expected frequencies), are likely to be simply due to sampling error, or if they are likely to be real. The syntax of the function is: CHITEST ( actual_range, expected_range )

The CHISQ.TEST function [1] is categorized under Excel statistical functions. It will calculate the chi-square distribution of two provided datasets, specifically, the observed and expected frequencies. The function helps us understand whether the differences between the two sets is simply due to sampling error, or not.

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.

Chi-square is a statistical hypothesis test for determining whether to accept or reject the null hypothesis. It involves comparing observed and expected values to find the p-value. Once you find the p-value, or significance level, you can compare it to the alpha value to determine if the null hypothesis is valid.

We can now calculate the p-value for the chi-square test statistic by using a formula of form =CHISQ.TEST (Obs, Exp, df) where Obs is the 3 ร 3 array of observed values, Exp = the 3 ร 3 array of expected values and df = (row count - 1) (column count - 1) = 2 โ 2 = 4. Since CHISQ.TEST (B6:D8, H6:J8) = 0.003273 < .05 = ฮฑ
