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 dots to represent each data point.

Front

How do you read a line plot?

Back

To read a line plot, look at the number line to see the values represented and count the marks (X's or dots) above each value to determine frequency.

Front

What does each mark on a line plot represent?

Back

Each mark on a line plot represents one occurrence of a data point.

Front

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

Back

To find the total number of data points, add up all the marks (X's or dots) on the line plot.

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

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

Back

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

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 highest stack of marks on the line plot.

Front

What is the median in a line plot?

Back

The median is the middle value when the data points are arranged in order. If there is an even number of data points, it is the average of the two middle values.

Front

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

Back

You can use a line plot to quickly find frequencies, totals, modes, and medians by analyzing the marks and their positions.

Front

What does it mean if a line plot has no marks above a certain value?

Back

If there are no marks above a certain value, it means that there were no occurrences of that data point.
