Answer
The mean appears to be a more appropriate measure of center.
Work Step by Step
From the statistical summary, it can be seen that the average of the mean of the sample and the sample median of each sample size are approximately equal to 50. Standard deviation decreases for both sample mean and median when the size of the sample increases. However, when the standard deviation is considered, it is smaller for the sample mean than the sample median. So, according to the analysis, mean appears to be a more appropriate measure of center.
