What is the definition for outlier in math terms?

Answer 1

In mathematics, an outlier is a data point that significantly deviates from the other observations in a dataset. It is typically defined as a value that lies outside the range of the expected data, often determined using statistical measures such as the interquartile range (IQR) or standard deviation. Outliers can indicate variability in the data, measurement errors, or novel phenomena and may impact statistical analyses and interpretations.
