Students learn how to interpret datasets by comparing the spread of results from the range.

Later, as learning progresses they analyse datasets using the mean as a measure of central tendency and the range as a measure of spread.

**Differentiated Learning Objectives**

- All students should be able to calculate the range from a set of data.
- Most students should be able to compare the consistency of two or more data sets using the range.
- Some students should be able to compare two more data sets using an average and range
