This is often clear in boxplots, where the median is not in the middle of t Test bank and solution of business analysis data analysis and decisiong making 6e (1)he box.C.8. The standard deviation, like the mean, is highly sensitive to outliers. Remember that In the definition of standard deviation, deviationsTest bank and solution of business analysis data analysis and decisiong making 6e (1)
from the mean are squared, so outliers on either side can really increase the standard deviation.
