Line Plots

Front

What is a line plot?

Back

A line plot is a graph that shows data using a number line. Each data point is represented by an 'X' above the number where it belongs.

Front

How do you read a line plot?

Back

To read a line plot, look at the number line and count the 'X's above each number to see how many times that number occurs.

Front

What does each 'X' represent in a line plot?

Back

Each 'X' represents one occurrence of a data point.

Front

How can you find the total number of data points in a line plot?

Back

Add up all the 'X's above the numbers to find the total number of data points.

Front

What is the purpose of a line plot?

Back

The purpose of a line plot is to display data clearly and to help visualize how often each value occurs.

Front

How do you determine the mode from a line plot?

Back

The mode is the number that has the most 'X's above it in the line plot.

Front

What is the difference between a line plot and a bar graph?

Back

A line plot uses a number line and 'X's to show data, while a bar graph uses bars to represent the frequency of data.

Front

How can you use a line plot to answer questions about data?

Back

You can count the 'X's to find totals, modes, and other information about the data.

Front

What does it mean if a number has no 'X's above it in a line plot?

Back

It means that number did not occur in the data set.

Front

How can you compare two sets of data using line plots?

Back

You can create two line plots on the same number line and compare the number of 'X's for each data point.
