Explanation:
Detailed explanation-1: -An outlier is a value that is much larger or smaller than the other values in a data set, or a value that lies outside the given data set.
Detailed explanation-2: -A value that “lies outside” (is much smaller or larger than) most of the other values in a set of data. For example in the scores 25, 29, 3, 32, 85, 33, 27, 28 both 3 and 85 are “outliers".
Detailed explanation-3: -An outlier is an unusually large or small observation. Outliers can have a disproportionate effect on statistical results, such as the mean, which can result in misleading interpretations. For example, a data set includes the values: 1, 2, 3, and 34.
