Line Plots

A line plot is a graph that shows data along a number line, where each mark represents a value.

You read a line plot by looking at the marks above the number line to see how many times each value occurs.

Each mark on a line plot represents one occurrence of a value.

To find the total, count all the marks above the numbers on the line plot.

The purpose of a line plot is to display data clearly and to make it easy to see how often each value occurs.

The mode is the value that has the most marks above it on the line plot.

A line plot shows data along a number line, while a bar graph uses bars to represent the frequency of different categories.

You can use a line plot to visualize the data and find answers to questions about totals, modes, or comparisons.

If there are no marks above a number, it means that value did not occur in the data set.

Count all the marks on the line plot to find the total number of students.
