How to Interpret Box-and-Whisker Plots

Subject: Mathematics

Book: Maths Mastery

A box-and-whisker plot displays the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum of a dataset. The “box” covers Q1 to Q3, highlighting the interquartile range, and a line within marks the median. “Whiskers” extend to show the minimum and maximum, excluding outliers. This visual summary quickly reveals central tendency, variability, and potential outliers. Whether analyzing test scores, financial returns, or scientific measurements, box plots condense data distribution into a snapshot that guides deeper exploration or comparisons between groups.
