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 the number of times each value occurs.

How do you create a line plot?

Back

To create a line plot, draw a horizontal line, mark the values at equal intervals, and place an X above each value for each time it occurs in the data set.

Front

What does each X represent in a line plot?

Back

Each X in a line plot represents one occurrence of a data value.

Front

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

Back

To find the total number of data points, count all the X's above the values 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 easily see patterns, trends, and frequencies.

Front

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

Back

A line plot shows data along a number line with X's, while a bar graph uses bars to represent the frequency of data in different categories.

Front

How can you determine the mode from a line plot?

Back

The mode is the value that appears most frequently, which can be identified by the highest stack of X's in the line plot.

Front

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

Back

The median is the middle value when the data points are arranged in order. In a line plot, you can find it by counting to the middle X.

Front

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

Back

The range is found by subtracting the smallest value from the largest value represented in the line plot.

Front

What does it mean if a line plot has a peak?

Back

A peak in a line plot indicates that there is a value that occurs more frequently than others, showing a concentration of data.
