Learners may study parts of this unit before unit 4, formation of frequency distributions into cumulative frequency distributions, and then study unit 4 as it becomes a necessary tool for finding the median and quartiles of grouped frequency distributions. Some teachers may therefore choose to teach unit 4 alongside this unit.
