Bailey is trying to remember whether when there is a significant effect of a factor in a one-way ANOVA, whether it is due to the between-groups or within-groups variance being greater. (i) For a factor to have a significant effect in a one-way ANOVA, which needs to be greater, the between-groups or within-groups variance? Write A or B: A. Between-groups variance B. Within-groups variance (ii) Why? Write the letter of your answer: A. Because more between-groups variance results in a smaller F statistic. B. More within-group variance means that more of the difference in outcome scores is due to the impact of the factor. C. Because the F statistic is calculated by MS within divided by MS between. D. More between-group variance means that more of the difference in outcome scores is due to the impact of the factor
