The key idea of statistical literacy at level 4 is thinking beyond the data presented.

At level four the focus of the evaluation expands from “displays” (key idea at level 3) to statements made by others about their findings.  They should be looking for statistically sound statements based on the data presented in the findings and suggesting alternative correct wording when this isn’t the case. 
Students should be asking “what if” and “why” questions about other students’ findings. 

Students should be thinking whether there are alternative findings from the data, or if there are other relevant variables that could be considered other than what was reported in the findings of other students.

This key idea develops from the key idea of statistical literacy at level 3 where students can make savvy judgements about the appropriateness of ways of presenting data.

This key idea links to the key idea of statistical investigations at level 4 and the key idea of probability at level 4.

This key idea is extended in the key idea of statistical literacy at level 5 where students are learning to detect flaws in a whole statistical or probability investigation.
