    The most appropriate measure of center of this data set would be the median, or the arithmetic average. The median would be more suitable because the mean is more heavily influenced by outliers. In a skewed distribution, the mean would be pulled more towards the tail of the data where outliers exist, and the average value would be greater than that of the median.

I did not know what a confidence interval or what a standard error of measurement was. Now many months later, I know that the standard error of measurement estimates how someone's score will change over time. This is due to the fact that a person will probably not get the same score every time they retake a test. I also learned that the standard
