Suppose we expand the study described in Question #24. Instead of looking only at juniors and seniors, we also take random samples of freshmen and sophomores. Which inferential statistical test would we use to determine whether there is a statistically significant effect of year-in-college on exam scores? A) independent-samples t test / two-sample t test B) dependent-samples t test / matched-pairs t test / related-samples t test / paired t test C) chi-square D) one-way ANOVA E) factorial ANOVA
