Sco Description re 4 The student response demonstrates an exemplary understanding of the Data Analysis, Statistics, and Probability concepts involved in reading, interpreting, and drawing 4 conclusions from bar graphs. 3 The student response demonstrates a good understanding of the Data Analysis, Statistics, and Probability concepts involved in reading, interpreting, and drawing conclusions from bar graphs. Although there is significant evidence that the student was able to recognize and apply the concepts involved, some aspect of the response is flawed. As a result, the response merits 3 points. 2 The student response demonstrates a fair understanding of the Data Analysis, Statistics, and Probability concepts involved in reading, interpreting, and drawing conclusions from bar graphs. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points. 1 The student response demonstrates a minimal understanding of the Data Analysis, Statistics, and Probability concepts involved in reading, interpreting, and drawing conclusions from bar graphs. 0 The student response contains insufficient evidence of an understanding of the Data Analysis, Statistics, and Probability concepts involved in reading, interpreting, and drawing conclusions from bar graphs to merit any points. http://www.doe.mass.edu/mcas/student/2007/question.asp?
