Scoring Guide and Sample Student Work

Select a score point in the table below to view the sample student response.

Score	Description
4	The student response demonstrates an exemplary understanding of the Statistics and Probability concepts involved in reading and interpreting circle graphs. The student compares information presented in circle graphs and uses that information to make appropriate conclusions about the data represented by the graph.
4
3	The student response demonstrates a good understanding of the Statistics and Probability concepts involved in reading and comparing information presented in circle graphs and using that information to make appropriate conclusions about the data represented by the graph. 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 Statistics and Probability concepts involved in reading and comparing information presented in circle graphs and using that information to make appropriate conclusions about the data represented by the graph. 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 Statistics and Probability concepts involved in reading and comparing information presented in circle graphs and using that information to make appropriate conclusions about the data represented by the graph.
0	The student response contains insufficient evidence of an understanding of the Statistics and Probability concepts involved in reading and comparing information presented in circle graphs and using that information to make appropriate conclusions about the data represented by the graph to merit any points.
