What do the whiskers in a box plot represent?

Back

The whiskers extend from the box to the smallest and largest values that are not outliers, showing the spread of the data.

What is the interquartile range (IQR)?

Back

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

What does it mean if a box plot has a larger IQR?

Back

A larger IQR indicates that the middle 50% of the data is more spread out, showing greater variability in that portion of the dataset.
