S3-2: Evaluate the effectiveness of different displays in representing the findings of a statistical investigation or probability activity undertaken by others.

Elaboration on this Achievement Objective

This means students will learn to become critical consumers of statistically based information. This involves critically analysing the choice of display other people have made to convey statistical information. At Level Three students should be able to gain information from all of the displays mentioned in Statistical Investigation, and be aware of the type of data each display is appropriate for and the kind of pattern or relationship that the display is best at communicating. For example, pictographs, and bar graphs highlight difference between frequencies of categories, for example four more students have blue eyes than green, while pie charts and strip graphs highlight proportions, for example the spinner landed on red about one third of the time. Students should link the claims made by others with the appropriateness of the displays used.
