Question

Quizplus · Accepted Answer

The standard error of the mean is inversely proportional to the square root of the sample size. As the sample size increases, the square root of the sample size increases as well, leading to a decrease in the standard error of the mean. Therefore, as the sample size increases, the standard error of the mean decreases.
