What Does The P Value Represent In Chi Square Compare the test statistic X 2 to a critical value from the Chi square distribution table Compare the p value of the test statistic X 2 to a chosen alpha level Let s walk through an example of how to use each of these approaches
For a chi square test a p value that is less than or equal to the 05 significance level indicates that the observed values are different to the expected values Thus low p values p 05 indicate a likely difference between the The small P value indicates indicates categories are not all equally likely Note When specific probabilities are not supplied the R procedure chicsq test assumed equal probabilities are intended There are 8
