What is the median in a box plot?

Back

The median is the middle value of the dataset when it is ordered from least to greatest, represented by a line inside the box.

What are quartiles in a box plot?

Back

Quartiles divide the dataset into four equal parts: Q1 (25th percentile), Q2 (50th percentile or median), and Q3 (75th percentile).
