Question

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?
bar graph
line graph
line plot
stem and leaf plot

Answer 1

Stem-and-leaf plot.

It shows the distribution while keeping the actual values (minutes) visible, which is ideal for this small numerical data set.
