4
3
The student response demonstrates a good understanding of the Data Analysis, Statistics, and Probability Strand concepts involved in finding the median and range for a given set of data. 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 fair understanding of the Data Analysis, Statistics, and Probability Strand concepts involved in finding the median and range for a given set of data. 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 only minimal understanding of the Data Analysis, Statistics, and Probability Strand concepts involved in finding the median and range for a given set of data.
0 The student response contains insufficient evidence of an understanding of the Data Analysis, Statistics, and Probability Strand concepts involved in finding the median and range for a given set of data to merit any points.
