Line Plots

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line, using X's or other symbols to represent each data point.

Front

How do you read a line plot?

Back

To read a line plot, count the number of X's above each value on the number line to determine how many times that value occurs.

Front

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

Back

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

Front

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

Back

Add up all the X's in the line plot 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 visually display data to make it easier to see patterns, trends, and frequencies.

Front

How do you determine the mode from a line plot?

Back

The mode is the value that appears most frequently, which can be found by identifying the value with the most X's.

Front

What is the difference between the longest and shortest data points in a line plot?

Back

The difference is calculated by subtracting the smallest value from the largest value.

Front

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

Back

You can use a line plot to quickly find frequencies, modes, and ranges, and to compare different data points.

Front

What does it mean if a line plot has no X's above a certain value?

Back

It means that there are no data points for that value; it did not occur in the data set.

Front

How can you represent data with a line plot?

Back

To represent data, choose a number line, mark the values, and place an X above each value for each occurrence.
