Quizplus · Accepted Answer

A chi-square test assesses the significance of the difference between observed and expected frequencies, which is often used to determine if the observed data fits a theoretical model or not. The expected frequencies are calculated based on chance (randomness) or some specified null hypothesis. Therefore, the comparison in a chi-square test is between what is observed and what would be expected by chance.
