AP Statistics Free Response

The evaluation of student responses on the free-response section of the class exam reflects the two-fold importance of statistical knowledge and good communication. The free-response questions and the investigative task are scored "holistically"; that is, each question's response is evaluated as "a complete package." With holistic scoring, after reading through the details of a student's response, I make a judgment about the overall quality of the response.

AP Statistics Score Descriptors
	(N/A)	Complete 4 pts	Substantial 3 pts	Developing 2 pts	Minimal 1 pts	0 pts
Statistical Knowledge	N/A ~ Identification of the important components of the problem ~ Demonstration of the statistical concepts and techniques that result in a correct solution of the problem	Complete ~ shows complete understanding of the problem's statistical components ~ combines a correct relationship among these components, perhaps with originality and creativity ~ uses appropriate and correctly executed statistical techniques ~ may have minor arithmetic errors but answers are still reasonable	Substantial ~ shows substantial understanding of the problem's statistical components ~ combines a relationship among these components, perhaps with minor gaps ~ uses appropriate statistical techniques ~ may have arithmetic errors but answers are still reasonable	Developing ~ shows some understanding of the problem's statistical components ~ shows little in the way of a relationship among these components ~ uses some appropriate statistical techniques but misses or misuses others ~ may have arithmetic errors that result in unreasonable answers	Minimal ~ shows limited understanding of the problem's statistical components by failing to identify important components ~ shows little ability to organize a solution and may use irrelevant information ~ misuses or fails to use appropriate statistical techniques ~ has arithmetic errors that result in unreasonable answers	0 ~ shows little to no understanding of statistical components
Communication	N/A Explanation of what was done and why, along with a statement of conclusions drawn in context	Complete ~ provides a clear, organized, and complete explanation, using correct terminology, of what was done and why ~ states appropriate assumptions and warnings ~ uses diagrams or plots when appropriate to aid in describing the solution ~ states an appropriate and complete conclusion in context	Substantial ~ provides a clear but not perfectly organized explanation, using correct terminology, of what was done and why, but explanation may be slight incomplete ~ may miss necessary assumptions or warnings ~ uses diagrams or plots when appropriate to aid in describing the solution ~states a conclusion that follows from the analysis but may be somewhat incomplete	Developing ~ provides some explanation of what was done, but explanation may be vague and difficult to interpret and terminology may be somewhat inappropriate ~ uses diagrams in an incomplete or ineffective way, or diagrams may be missing ~ states a conclusion that is incomplete	Minimal ~ provides minimal or unclear explanation of what was done or why it was one, and explanation may not match the presented solution ~ fails to use diagrams or plots, or uses them incorrectly ~ states an incorrect conclusion or fails to state a conclusion	0 ~ provides no explanation of a legitimate strategy
