Quizplus · Accepted Answer

Katie is most concerned about committing a Type II error. This error occurs when she fails to reject a null hypothesis that is actually false (i.e. there are significant differences in her study), because her significance level is too high or sample size too small to detect these differences. This means she will make the incorrect conclusion that there are no significant differences when there are.
