In this globalized world, our citizens gain instantaneous access to statistical information via various communication technologies. This has heightened a serious call for the development of statistically literate citizens. Nevertheless, research has highlighted that our school leavers are not very statistically literate which drew the attention to teachers and their knowledge in the enhancement of statistical literacy. This paper presents the analysis of the responses of a case study, named Lina (a pseudonym) related to two tasks on the idea of mode. Data was collected using clinical interview based on open-ended questions as instrument. The findings suggest that Lina could relate the idea of mode to real-life situation. Lina utilised the mode as a form of data representation in certain situations. However, Lina did not utilise the mode as a quick method to report an average. In relation to statistical literacy, the understanding of the mode as a form of data representation can lead to this measure being used as a quick method to report central tendency or average.
