Analyze 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 marks (X's) 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 highest value in a line plot?

Back

Look at the number line and find the rightmost point with X's; that value is the highest.

Front

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

Back

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

Front

How do you determine the total number of data points from a line plot?

Back

Count all the X's in the line plot; each X represents one data point.

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 can you find the mode from a line plot?

Back

The mode is the value with the most X's above it; it is the most frequently occurring value.

Front

What is the median in a line plot?

Back

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

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.
