Not enough information, provide us with the rest of the question please. But if you are just simply asking what it means then find the median of the data set without the outliner is The median doesn't represent a true average, but is not as greatly affected by the presence of outliers as is the mean. Example: The median of 1, 3, 5, 5, 5, 7, and 29 is 5 (the number in the middle). Then find the median of the data set with outliner means To find the median, arrange your data from smallest to largest and look for the middle value. If the total number of data points is odd, there will be one number that sits directly in the middle of your data set, and this will be your median.
