Several studies indicate that students encounter significant difficulties when determining how to represent or interpret continuous data in a discrete manner and to represent or interpret discrete data in a continuous manner. In this paper, we focus on whether and when pre-service and in-service mathematics teachers represent functional dependence in a continuous or discrete manner. In pursuit of this objective, we employed two tasks from the research tool, which pre-service and in-service teachers solved, and subsequently scrutinized both their solutions and collaborative discussions concerning these tasks.
