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.
The Effects of Outliers (Jump to: Lecture | Video ) An outlier is a value that is very different from the other data in your data set. This can skew your results. Let's examine what can happen to a data set with outliers. For the sample data set: 1, 1, 2, 2, 2, 2, 3, 3, 3, 4, 4. We find the following mean, median, mode, and standard deviation: Mean = 2.58.
