average (mean) number of people riding
in passenger cars, including the driver,
for different years.

Nicholas wants to present this information
to the class in the form of a graph.
Graph
the data from the table on the grid
below.
Give it an informative title.
Label the scales and axes.
Once again a 4 point response is needed
for this problem. A 4 point response will
use all the information in the chart to
create an appropriate and accurate graph
(line, bar graph or scatter plot) that
includes the following:
Appropriate scales
- the intervals should be less than
or equal to .5 and show the viewer
to see a downward trend in the data.
Consistent vertical
scale - the intervals are consistent
in number and spacing.
An appropriate title.
Appropriate labels
on both the horizontal and vertical
axes.
All six means are
correctly graphed.
Here are a couple of 4 point graphs
that you may have for a solution to
a problem like this:
Notice the names
of the different parts of a graph.
Be sure to know how to construct
a line graph or even a bar graph
for problems like this one.
