Outliers

• Outliers are values in the data set which are either suspiciously large or small.
• Such values may be the result of an error—the researcher measured incorrectly or perhaps the results were typed incorrectly.
• Outliers may be good data. There is always the chance that you have one basketball player in a set of ordinary people.
• The 7-foot height is not an error, but it is still unusually large.
