What are outliers?
Outliers are values at the extreme ends of a dataset.
Some outliers represent true values from natural variation in the population.
Other outliers may result from incorrect data entry, equipment malfunctions, or other measurement errors.
An outlier isn’t always a form of dirty or incorrect data, so you have to be careful with them in data cleansing.
What you should do with an outlier depends on its most likely cause.
