Summary: The new ``Australian Senior Secondary Curriculum: Mathematics" contains more statistics than the existing Australian Curricula. This case study examines how a group of Queensland mathematics teachers define the word ``statistics" and five statistical terms from the new curricula. These definitions are compared to those used in some commonlyused Queensland mathematics textbooks and in the glossaries of new ``Australian Senior Secondary Curriculum: Mathematics". The findings of this study suggest that many teachers do not have a good understanding of statistical concepts and that they rely on procedural definitions (instrumental understanding). This is reflected in the presentation of statistics in Queensland senior secondary mathematics textbooks. Definitions in the glossaries of the new curricula are generally better but perhaps other simpler concepts could be introduced first to develop relational understanding.
