# S2-2: Compare statements with the features of simple data displays from statistical investigations or probability activities undertaken by others.

Elaboration on this Achievement Objective

This means students will critically consider comments made by others, usually their classmates, by referring to the features of displays on which the person is making claims. These displays will be showing either category data (pictographs, bar, strip, and pie graphs) or whole number data (dot plots or stem and leaf graphs). Students should also consider whether the chosen display/s best shows patterns in the data, for example strip and pie graphs show proportions well, pictographs and bar graphs show differences well.
