Detailed explanation-1: -An. outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph.

Detailed explanation-2: -The extreme values of the data set are known as the outliers (minimum values or maximum values). If a data set consists of outliers then the estimate of the population parameter will not be efficient.

Detailed explanation-3: -In statistics, an outlier is a data point that differs significantly from other observations. An outlier may be due to a variability in the measurement, an indication of novel data, or it may be the result of experimental error; the latter are sometimes excluded from the data set.
