Line Plots

Front

What is a line plot?

Back

A line plot is a type of graph that displays data along a number line, showing the frequency of each value.

Front

How do you read a line plot?

Back

To read a line plot, look at the marks (often 'X's) above each number to see how many times each value occurs.

Front

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

Back

Each 'X' represents one occurrence of a value in the data set.

Front

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

Back

Add up all the 'X's above each number 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 and frequencies.

Front

How do you determine the mode from a line plot?

Back

The mode is the value 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 shows data along a number line, while a bar graph uses bars to represent the frequency of categories.

Front

How can you find the median from a line plot?

Back

To find the median, list all the data points in order and find the middle value.

Front

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

Back

It means that no data points in the set correspond to that number.

Front

How do you find the range of data in a line plot?

Back

The range is found by subtracting the smallest value from the largest value in the data set.
