Quizplus · Accepted Answer

When cell frequencies are small and 2 x2 tables are used in the chi square test, Yates correction for continuity can be applied to adjust the value of chi square. This correction reduces the discrepancy between the actual and expected values and provides a better approximation of the real values by adjusting the degrees of freedom. Therefore, A) Yate's correction for continuity is the best choice.
