Mrs. Carden recorded how many minutes it took each student to finish the last quiz of the year. The results are: 12, 16, 18, 16, 14, 12, 15, 11, 18, 18, 11, 12, 16, 13, 13, 12. Which type of graph would best display the data?

A line plot is best for showing how often each individual number of minutes occurs. These results are a small set of numerical measurements, so the times can be marked above a number line and repeated values will be easy to compare. A stem-and-leaf plot can also organize numerical data, but a line plot makes the frequencies especially clear here.
