What are quartiles in a Box and Whisker Plot?

Back

Quartiles are values that divide a dataset into four equal parts: the first quartile (Q1), the second quartile (Q2, which is the median), and the third quartile (Q3).

What does the whisker represent in a Box and Whisker Plot?

Back

The whiskers extend from the quartiles to the smallest and largest values within 1.5 times the interquartile range (IQR) from the quartiles.

What is the interquartile range (IQR)?

Back

The IQR is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.
