Graphing and Analyzing Data

This video tutorial explains how to construct a graph from a data table showing the stopping distance of a car at various speeds. It covers the criteria for a good graph, including proper labeling of axes, appropriate scaling, and plotting points accurately. The tutorial guides viewers through identifying input and output variables, scaling the axes, and plotting data points to create an accurate graph.

What does the data table in the lesson represent?

• The acceleration of a car

• The speed of a car over time

• The fuel efficiency of a car

• The stopping distance of a car at various speeds

Which axis should be labeled with the input variable?

• Vertical axis

• Horizontal axis

• None of the axes

• Diagonal axis

What is the first step in setting up a graph according to the lesson?

• Drawing the grid

• Choosing the graph color

• Labeling the axes

• Plotting the data points

What is the input variable in the example provided?

• Stopping distance in feet

• Time in seconds

• Speed in miles per hour

• Acceleration in meters per second squared

What is the range for the horizontal axis in the example?

• 0 to 50

• 15 to 80

• 0 to 100

• 44 to 481

How many sub-intervals are used for the horizontal axis?

• 5

• 10

• 15

• 20

What is the width of each sub-interval on the vertical axis?

• 100 units

• 10 units

• 25 units

• 50 units

What is the first ordered pair to be plotted on the graph?

• 45, 196

• 35, 135

• 15, 45

• 25, 85

Where should the axes meet on the graph?

• At the center of the graph

• At the bottom left corner

• At the top right corner

• At the origin (0,0)

What is the last ordered pair to be plotted on the graph?

• 60, 304

• 75, 433

• 80, 481

• 50, 229
