Note: Graphs from the Incline task were used to illustrate the
scoring criteria for graphs in the friction task. For Friction the
horizontal axis should be labeled "Surface Texture (Board)" and
the levels should be "Plain," "Felt," and "Sandpaper" (in that order).
The vertical axis is the same, but the values should be 8, 12, and
17 (in that order).
Example 1
The following graph would receive a score of 2 points.
Point for... 
Points Received 
Horizontal Axis: 
1 
Vertical Axis: 
0 (not clearly equal interval) 
Plotting all the points: 
1for this point and the last point a combined total of 1
point is given because of the 90 degree lines in the graph. 
Plotting the points correctly: 
See above point.
