Question

What are outliers?

Answer 1

Outliers are data points that are significantly different from other data points in a dataset. They are observations that lie an abnormal distance away from other observations. In other words, outliers are values that fall outside the typical range of values in a dataset. Outliers can occur due to various reasons such as measurement errors, natural variations, or they may actually represent important and meaningful observations. Detecting and handling outliers is important in data analysis and statistical modeling as they can have a significant impact on statistical measures and can affect the accuracy of models and predictions.
