A graph that shows the frequency of data along a number line.

• A. line plot
• B. bar graph
• C. pictograph
• D. scatter plot

Answer: (A)

A line plot is a graph that shows how often data occur along a number line. In a line plot, you have a number line and place marks (like tally marks or X’s) above each value to show its frequency. This format makes it easy to see the distribution and how many times each number appears. The other graphs don’t fit this description. A bar graph uses vertical bars to compare different categories, not frequencies along a numeric line. A pictograph uses pictures to represent counts. A scatter plot places points on two axes to show relationships between two numbers.
