About this document
Understanding Quantiles and Outliers by Gerald Nitz Ponce is a document available to read on EtoBox.
This document defines and provides examples of quantiles, which divide a data distribution into equal parts. The median divides the data into two equal parts, and the quartiles (Q1, Q2, Q3) divide into four parts. The interquartile range is the difference between Q3 and Q1. Outliers are values less than Q1 - 1.5 * IQR or greater than Q3 + 1.5 * IQR. An example data set is provided and analyzed to find the quartiles, interquartile range, and identify any outliers.
