Overall, using the median when analyzing a data set is beneficial as it is more resistant to outliers, negative values, and skewness than the Mean. How do you find the median of a set of values when there is an even number of values? MEDIAN The median is less affected byoutliersandskeweddata than themean, and is usually the preferredmeasure of central tendency when the distribution is not symmetrical. To illustrate, if a data set is comprised of five values that are all the same, the median value will still be that one value, making it look like the entire set is uniform.
