Conclusion
An outlier is a value that lies outside the normal range of values in a dataset. In simpler terms, it's an unusual or unexpected value that doesn't fit with the rest of the data. Imagine you're measuring the heights of a group of people. Most people's heights are between 5'6" and 6'2", but one person stands at 7'0". In this case, the person who is 7'0" would be considered an outlier because their height is significantly different from the rest of the group.
