Question 5 • Concepts in Probability and Statistics

The distance in miles a car travels over time in minutes is shown in the table. Distance (miles) Time (minutes) 10 15 20 30 30 45 40 60 Kwame is not sure whether to use a line graph or a line plot to display the data. Which best explains which graph is a better representation of the data?

Answer
A
The line plot because numbers can be plotted on a number line.
B
The line graph because it shows how the number of miles increases over the number of minutes.
C
The line plot because there are only a few data points.
D
The line graph because the numbers in the data table are equally spaced.

Explanation

A line graph is best because the data show how distance changes as time passes. The graph can connect the points (15, 10), (30, 20), (45, 30), and (60, 40) to show the car’s distance increasing over time. A line plot is mainly used to show the distribution of individual values, not how one quantity changes with another.
