How Do I Determine an Outlier?

Answer

An outlier is an experimental or measurement data set far from the other values in a sample used for statistical studies determined using the quartile method. Examine the data set and pick out potential outliers, arrange the data points from lowest to highest, calculate the median of the data set, calculate the lower quartile known as point Q1 which is the data point below which 25 percent of the observations sit. Calculate the inner fences for the data set by finding the difference between Q1 and interquartile range known as Q3, then multiply Q3 by three to find out the outer fences for the data set.
