Question

2 multiple choice 1 point in order to determine whether the differences between group means are statistically significant, anova examines the differences neither between nor within groups within groups between and within groups between groups

Explanation:

ANOVA (Analysis of Variance) works by comparing the variance between groups (between - group variance) and the variance within groups (within - group variance). The F - statistic in ANOVA is calculated as the ratio of between - group variance to within - group variance. By examining both the differences between groups and within groups, we can determine if the differences in group means are statistically significant. So the correct option is the one that says "between and within groups".

Answer:

C. between and within groups (assuming the options are labeled A, B, C, D with A: neither between nor within groups, B: within groups, C: between and within groups, D: between groups)
