Mathematics Education Research Group of Australasia, Paper presented at the Annual Meeting of the Mathematics Education Research Group of Australasia (MERGA) (36th, Melbourne, Victoria, Australia, 2013)

This paper addresses one of the foundational components of beginning interference, namely variation, with 5 classes of Year 4 students undertaking a measurement activity using scaled instruments in two contexts: all students measuring one person's arm span and recording the values obtained, and each student having his/her own arm span measured and recorded. The results included documentation of students' explicit appreciation of the variety of ways in which variation can occur, including outliers, and their ability to create and describe valid representations of their data.
