Question 3 • Concepts in Probability and Statistics

Jaime wants to display her math test scores by using either a line plot or a stem and leaf plot. Her test scores are: 93, 95, 87, 90, 84, 81, 97, 98. Which best explains what type of graph will better display the data?

Answer
A
a line plot because the numbers are all clustered near each other
B
a line plot because there are only a few data points
C
a stem and leaf plot because the data can be grouped into sets of 10
D
a stem and leaf plot because each data point contains two digits

Explanation

A stem-and-leaf plot groups numbers by their tens digit and lists the ones digits beside each stem. These scores naturally group into the 80s (81, 84, 87) and the 90s (90, 93, 95, 97, 98), making the data easy to organize and compare. So the best choice is a stem-and-leaf plot because the data can be grouped into sets of 10.
