Question

Quizplus · Accepted Answer

Rejecting the null hypothesis of a chi-square goodness-of-fit test does not necessarily imply that the population is normally distributed. It only means that the observed distribution of data is significantly different than the expected distribution assumed by the null hypothesis. There could be other distributions that fit the observed data better.
