How do you interpret a stem-and-leaf plot?

Back

Read the stems vertically and the leaves horizontally to understand the distribution and frequency of the data.

Front

What is the significance of the shape of a stem-and-leaf plot?

Back

The shape can indicate the distribution of the data, such as whether it is symmetric, skewed, or has outliers.
