Line of Best Fit Project
	Poor 0 pts	Fair 1 pts	Good 2 pts
Introduction 10 %	Poor Introduction is included, but is missing more than one part.	Fair Introduction is included but is missing one part.	Good Introduction includes all necessary parts and is clear: hypothesis, your prediction, and what the independent and dependent variables are.
Data (table) 10 %	Poor Data is not displayed in a table.	Fair Data is displayed but lacks a clear organization (x and y variables are not labeled).	Good Data is displayed in a table with labels and is organized and neat.
Graph 20 %	Poor There is no graph.	Fair Mising either the scatter plot or the line of best fit or the graph is not neat (ruler not used).	Good Scatter plot and the line of best are neatly graphed. A ruler is used.
Equations of the line of best fit. 20 %	Poor There are no equations.	Fair One equation is missing or both equations are present but calculations are incorrect or no work is shown on how the visual approximation line was calculated.	Good Both equations are present. All calculations are correct and work is shown.
25 Data Values 10 %	Poor 15 data values or less	Fair Between 16 and 24 data values. Or 25 data values, but no initials or website where data was obtained is not included.	Good 25 data values included and initials or website is included.
Conclusion 10 %	Poor No conclusion is included.	Fair Conclusion is included, but is missing one or more parts.	Good Conclusion is included and includes all parts: whether the data supported your hypothesis or not; what type of correlation, if any, your data shows; and an explanation of what this type of correlation tells you about the relationship between the two quantities compared.
Presentation 10 %	Poor No presentation is made.	Fair Presentation is made, but some parts are unclear or left out (ex: the hypothesis and/or conclusion is unclear or not included).	Good Presentation is made and all aspects are clear (including hypothesis and conclusion). Each group member has a part and it is planned before the presentation is made.
Poster 10 %	Poor Poster is missing more than one part.	Fair Poster is missing one part or is not neat or colorful.	Good Poster is neat and colorful with all parts included (title, introduction, table, graph, equations, and conclusion).
