Customizing Box Plots in R to Include Outliers as Whiskers
Understanding Box Plots and Outliers Box plots are a graphical representation of data distribution that can help identify outliers. A typical box plot consists of a box, whiskers, and a dot representing the mean. The whiskers extend to 1.5 times the interquartile range (IQR) from the first quartile (Q1) or third quartile (Q3), depending on the position of the data distribution. Outliers are typically defined as any value that falls outside this IQR.
