Data Table: 0 Points: Data is not given in a data table.
1 Point: There is a data table. A large amount of data is wrong or missing. Table is not drawn neatly. Units are not given. Data table has no title, or a title that makes no sense.
2 Points: Data is recorded in a data table. Some mistakes may have been made, but table is mostly accurate. Table is not drawn very neatly. Units are not given correctly, or at all. Data table has no title, or a title that makes no sense.
3 Points: All data is accurately recorded in a data table. Data table is neatly drawn. Units are given correctly. Data table is titled (e.g. Table 1: Position vs. Time of Walker)

Graph: 0 Points: Data is not graphed.
1 Point: There is a graph, but the data is mostly plotted incorrectly, or mostly missing. Axes may be backwards. Graph is very sloppy. Axes are too big or too small—graph is too “zoomed out” or too “zoomed in”. Axes are unlabeled. Graph has no title, or title doesn’t make sense.
2 Points: Data is plotted on a graph, but a few mistakes have been made. Axes may be backwards. Graph is a little sloppy. Axes are too big or too small—graph is too “zoomed out” or too “zoomed in”. Axes are labeled, but without units. Graph has no title, or the title doesn’t make sense.
3 Points: All pertinent data is correctly plotted in a graph. Axes are correct. Graph is neatly drawn. Axes are sized to show all data without being too “zoomed out” Axes are labeled, with units. Graph is titled (e.g. Figure 1: Position vs. Time of Walker)
