Abstract

Summary: Quartiles are usually introduced early, often in primary school together with box‐and‐whisker plots. Various methods are used, and in lack of explanation in many textbooks at elementary level, this leads to unnecessary confusion. We discuss some elementary methods that are consistent with the most common definition and are also easy to understand.
