Work Step by Step
From the statistical summary, it can be seen that average of the sample mean increases to 50.03 and median of the sample decreases to 34.8. The standard deviation decreases for both the sample mean and median when sample size increases. The standard deviation of mean decreases from 15.31 to 3.308 and the standard deviation of median decreases from 14.75 to 3.39. So, according to the analysis, the mean appears to be a more appropriate measure of center.
