Modelling ideas are now emphasised in the teaching and learning of statistics (e.g., Kawakami, 2015). This presentation reports on a case study examining how Year 9 students (14-15 year olds) created and utilized data models in estimating and predicting Japanese population by 5-year age group. The analysis illustrated that the students perceived the role of data and the necessity of shuttling between data and context in developing data models to understand, estimate and decide on the trend of population. Findings will inform educators on how to strengthen the link between statistical ideas and modelling ideas in the teaching and learning of statistics.
