In general, if the variance of the difference scores decreases, what will happen to the value of the t statistic? a. It will increase in magnitude (move farther toward the tail of the distribution). b. It will decrease in magnitude (move toward 0 at the center of the distribution). c. It will stay the same; the t statistic is not affected by the variance of the difference scores. d. It may increase or may decrease; there is no consistent relationship between variance and the size of the t statistic.
