Outliers

Outliers are data points that significantly differ from other observations in a dataset. They stand out because they are much higher or lower than most of the other values. These unusual points can result from measurement errors, rare events, or natural variability. Outliers are important because they can distort analysis and lead to misleading conclusions if not properly considered. Identifying outliers helps to understand the full story behind the data, decide whether to investigate further, and determine the best way to analyze the rest of the data accurately.
