â¦ Compare the result for the mean, median, and mode when the outlier was included and when it was not included. Come to a conclusion about which measure of central tendency (mean, median, or mode) seems to be most affected by an outlier. Ask them to explain why that might be.
Outliers increase the standard deviation. Mean is most affected by outliers, since all values in a sample are given the same weight when calculating mean. A value that is far removed from the mean is going to likely skew your results and increase the standard deviation. Say you have five values: 2, 1, 2, 1.5, and 2.1. Your mean would be 1.72 and your standard deviation would be 0.47.
