Scoring Guide and Sample Student Work Select a score point in the table below to view the sample student response.

The student response demonstrates an exemplary understanding of the Statistics and Probability concepts involved in reading and interpreting circle graphs.

The student response demonstrates a good understanding of the Statistics and Probability concepts involved in reading and interpreting circle 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.

The student response demonstrates a fair understanding of the Statistics and Probability concepts involved in reading and interpreting circle graphs. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points.

The student response demonstrates a minimal understanding of the Statistics and Probability concepts involved in reading and interpreting circle graphs.

The student response contains insufficient evidence of an understanding of the Statistics and Probability concepts involved in reading andÂ interpreting circle graphs to merit any points.
