Question 7 • Concepts in Probability and Statistics

The mayor of a small town is trying to determine the change in population of his town over time. Which type of graph would best represent the data in the table? Year Population 1990 10,350 1995 10,750 2000 11,150 2005 11,500 2010 11,650

Answer
A
stem and leaf plot
B
line graph
C
line plot
D
bar graph

Explanation

A line graph is best for showing how a quantity changes over time. Plot each year against its population and connect the points to make the town’s population trend easy to see. A bar graph compares separate categories, while stem-and-leaf plots and line plots are better for displaying individual data values.
