What are Outliers?
Outliers are observations that are distinctly separate from the main body of data This can happen due to chance or due to the data being heavily skewed in one direction. Outliers can be caused by errors in the data collection or a more extreme version of a typical data point. They can also be caused by external factors such as natural disasters or changes in government policies. It is important to identify outliers for two main reasons: to identify potential data errors, and to understand if there is an underlying causal factor that needs to be investigated.
Outliers can be detected in a variety of ways including visual inspection, statistical tests, or machine learning algorithms. Visual inspection is the most common way to identify outliers, as it is the quickest and easiest method. In some cases, such as analyzing time-series data, statistically significant changes can also be identified relatively quickly. Machine learning algorithms can both detect and help explain outliers.
