Line Plots

Front

What is a line plot?

Back

A line plot is a graph that shows data along a number line, where each data point is represented by an 'X' or a dot.

Front

How do you read a line plot?

Back

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

Front

What does it mean if a line plot has more 'X's above a number?

Back

It means that more data points have that value, indicating it is more common or frequent.

Front

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

Back

Add up all the 'X's or dots 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 display data clearly and to help visualize the frequency of different values.

Front

How do you determine the range of data from a line plot?

Back

The range is found by subtracting the smallest value from the largest value shown on the line plot.

Front

What does it mean if a line plot shows a value with no 'X's?

Back

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

Front

How can you compare two different values in a line plot?

Back

You can compare two values by looking at the number of 'X's above each value to see which one has more occurrences.

Front

What is the median in a data set represented by a line plot?

Back

The median is the middle value when all data points are arranged in order; it can be found by locating the center 'X' in the line plot.

Front

How do you find the mode in a line plot?

Back

The mode is the value that appears most frequently, which is the value with the most 'X's above it.
