Front

How can you identify the mode using a stem-and-leaf plot?

Back

The mode can be identified by looking for the stem with the most leaves.

Front

What is a key advantage of using a stem-and-leaf plot over a histogram?

Back

A key advantage is that a stem-and-leaf plot retains the original data values, while a histogram does not.
