The stem-and-leaf plot with two rows for each stem shows the heights, in inches, of a group of plants. Display this data in a dot plot.

What is one key difference between how the stem-and-leaf plot and the dot plot display the data?

• A. The dot plot makes it easier to see which heights are most common, as each value is represented by a dot, whereas the stem-and-leaf plot usually groups data by tens and shows individual values as leaves.
• B. The stem-and-leaf plot shows the frequency of each value more clearly than the dot plot.
• C. The dot plot groups data by tens, while the stem-and-leaf plot shows each value individually.
• D. Both plots display the data in exactly the same way.
