Quizplus · Accepted Answer

The assumption of independence between observations is a basic assumption for a chi-square hypothesis test. Option A is incorrect because chi-square does not require normality. Option B is incorrect because the scale level of measurement does not affect the use of chi-square. Option D is incorrect because there is no specific sample size requirement for chi-square, as long as the minimum expected count assumption is met.
