Question

Quizplus · Accepted Answer

Analysis of variance (ANOVA) is a statistical method used to determine whether there is a significant difference between the means of two or more groups. It is used to simultaneously compare several population means, making option D the correct choice. Option A is incorrect because nominal data is compared using chi-square analysis. Option B is too vague and can refer to several different types of tests. Option C is incorrect because comparing population proportions is done using tests like the z-test or chi-square test of independence.
