Detailed explanation-1: -Outliers are data points that are far from other data points. In other words, they’re unusual values in a dataset.
Detailed explanation-2: -An outlier is a data point that is distant from the other observations. For instance, in a data set of 1, 2, 2, 3, 26, 26 is an outlier.
Detailed explanation-3: -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-4: -Determining Outliers Multiplying the interquartile range (IQR) by 1.5 will give us a way to determine whether a certain value is an outlier. If we subtract 1.5 x IQR from the first quartile, any data values that are less than this number are considered outliers.
