Understanding Data with Box Plots: An Example Explained
A box plot is a graphical representation of a dataset that displays the five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. The box itself represents the interquartile range (IQR), which is the difference between Q3 and Q1. The median is shown as a line within the box. Any data points that fall outside the IQR are considered outliers and are represented as individual points. This visual representation helps to quickly identify patterns, such as skewness and outliers, in the data.
