Compared to an independent-measures design,a repeated-measured study is more likely to find a significant effect because it reduces the contribution of variance due to ____. A)M_D B)degrees of freedom C)the effect of the treatment D)individual differences

Question

Quizplus · Accepted Answer

In a repeated-measures design, each participant is observed multiple times, which reduces the influence of individual differences and increases the power to detect the effect of the treatment. In an independent-measures design, individual differences can contribute more to the variance and decrease the chances of finding a significant effect. Therefore, the correct answer is individual differences (D). The other options do not make sense in this context.
