Analysis of variance models test hypotheses about the population standard deviation.

Question

Quizplus · Accepted Answer

Analysis of variance (ANOVA) models test hypotheses about the population means, not the population standard deviation. ANOVA compares the differences between means across different groups or samples, and determines if these differences are statistically significant or if they could have occurred by chance. It does not directly test hypotheses about the population standard deviation.
