How can you identify outliers in a box plot?

Back

Outliers in a box plot are typically represented as individual points that fall outside the range defined by 1.5 times the IQR above Q3 and below Q1.

Front

What does a higher median indicate in a box plot comparison?

Back

A higher median indicates that the central tendency of the data is greater, suggesting that the majority of the data points are higher in value.

How do you interpret the spread of data in a box plot?

Back

The spread of data in a box plot can be interpreted through the length of the box and whiskers; a longer box indicates greater variability in the middle 50% of the data.
