Free Introduction to Box and Whisker Plot

A box and whisker plot is a statistical chart used to summarize and visualize the distribution of numerical data. It displays the minimum, first quartile, median, third quartile, and maximum values, allowing viewers to quickly understand data spread and central tendency. This type of plot is commonly used by students, analysts, educators, and professionals to compare multiple datasets and identify variability or potential outliers. By presenting key distribution measures in a compact visual format, a box and whisker plot makes complex data easier to interpret, supports comparison across groups, and helps reveal patterns that may not be obvious from raw numbers alone.
