Question

Quizplus · Accepted Answer

The appropriate statistical technique to examine the difference among the average scores of three unrelated groups is an analysis of variance (ANOVA). ANOVA tests for significant differences between means of more than two groups. The independent-samples t-test is used when comparing the means of two independent groups, while the dependent-samples t-test is used when comparing the means of two related groups. Regression is used to examine the relationship between an independent variable and a dependent variable. Therefore, option D is the best choice for this scenario.
