# Understanding Variation

Description

In this worksheet, students learn what differences in data variation look like and then put that learning into practice. Variation can be a difficult concept to understand, so being able to describe what it looks like can be an excellent first step.
This worksheet is part of a larger unit on data displays for Year 4 designed to help students create, improve, and understand data displays.

Curriculum Codes

AC9M4ST02 9

Analyse the effectiveness of different displays or visualisations in illustrating and comparing data distributions, then discuss the shape of distributions and the variation in the data

AC9M4ST01 9

Acquire data for categorical and discrete numerical variables to address a question of interest or purpose using digital tools; represent data using many-to-one pictographs, column graphs and other displays or visualisations; interpret and discuss the information that has been created
