Outliers are those data instances that are significantly different from all observations within the data set. They can be caused by different reasons, including measurement errors, anomalies that are not detected in the experiment, or even genuine extreme instances. The identification and correction of outliers is crucial to ensure the validity of statistical analysis and to avoid misinterpreting the results.
