As the sample size increases, the standard error of the difference decreases. This is because a larger sample size provides a more accurate representation of the population, leading to less variation in the sample means and a smaller standard error of the difference. However, if the variability of scores in the population is held constant, then there will be no change in the standard error of the difference as the sample size increases.
