Students learn 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 data set.
- 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
