- Outliers are represented as individual data points outside the whiskers.
3. When would you use a box plot?
A box plot is used to visually summarize the distribution of a dataset and identify any outliers. It is particularly useful when comparing multiple datasets or identifying differences in variability between groups.
4. How can you create a box plot?
