Understanding Boxplots and Scales for Multiple Variables Boxplots are a powerful graphical tool used to display the distribution of data. They consist of several key components: the median (or middle line), the quartiles (lower and upper lines), and the whiskers (outliers). However, when dealing with multiple variables, it can be challenging to create a boxplot that effectively represents each variable’s distribution. In this article, we will explore how to create a boxplot for several variables with different scales.
