1 | KML Graph Scoring Guide | Explanation | ||

2 | In general your graphs in physical science are of a type known as scatter graphs. The graphs will be used to | |||

3 | give you a conceptual understanding of the relation between the variables, and will usually also be used to | |||

4 | help you formulate mathematical statement which describes that relationship. Graphs should include each of | |||

5 | the elements described below: | |||

6 | NEEDS IMPROVEMENT | SATISFACTORY | EXCELLENT | |

7 | GRAPH ELEMENTS | 6 pts. | 8 pts. | 10 pts. |

8 | Title-The title should describe the experiment. | |||

9 | Dep. Var. vs. Ind. Var. | |||

10 | Variables-The independent variable should | |||

11 | be plotted on the X-axis and the dependent | |||

12 | variable should be plotted on the Y-axis. | |||

13 | Labels-The variables plotted on each axis | |||

14 | should be clearly labeled. | |||

15 | Units-Units of measurement should be provided | |||

16 | in parentheses beside the axis labels. | |||

17 | Scale-Appropriate ranges should be chosen | |||

18 | for each axis beginning at zero, marked | |||

19 | along the axes in consistent intervals and | |||

20 | fitting all data points. | |||

21 | Plotting-Data should be plotted with dots | |||

22 | point protectors. | |||

23 | Line of Best Fit-A line or curve of best fit | |||

24 | is drawn smoothly to show the overall | |||

25 | tendency of the data. Lines of best fit should | |||

26 | be drawn with a straight edge. The line may | |||

27 | or may not go through all points. | |||

28 | EOL-The equation for the line of best fit | |||

29 | should be written with a clear explanation | |||

30 | of the variables in the equation and units | |||

31 | with each of the constants in the equation. | |||

32 | Neatness-The graph is neat and orderly | |||

33 | and can be read with ease. Graph paper | |||

34 | should be used when made by hand on paper. | |||

35 | Slope Calculation - The points used to | |||

36 | calculate the slope should be labeled with | |||

37 | plus signs (+). | |||
