Default p-value obtained in R

Question

In R when I use the chisq.test() function, what is the p-value that is computed? Is it two sided, upper tail or lower tail ?

Thanks in advance for helping out this beginner

Answer 1

P-values for χ2 test are always one-sided, due to how results are interpreted. χ2 tests test goodness of fit, which means that the result has only one favorable outcome, so the p-value is probability that the fit is good. This is more of a statistics question than a coding question, and is probably better suited for CrossValidated .
