## The Different Types Of Statistics And Statistics

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. In this case, using the 1.5 x IQR rule, any departure time less than 19.5 or greater than 16.5 is an outlier. Hence, with multiple outliers
