The aim of this chapter is to summarise the major studies related to teachers’ understanding of variability in both data analysis and chance contexts. Since there is a relation between this research and previous studies dealing with students, some results on students’ reasoning on variation are also described. At the end some recommendations for teaching and research are presented.
