Summary: This paper provides a review of four studies about what Singapore primary and secondary school students understand about standard statistical graphs. On the basis of international studies, a framework about understanding of statistical graphs is proposed to cover four types of operation on graphs: graph reading, graph interpretation, graph construction, and graph evaluation. A major part of this review is about the large scale survey of secondary school students $(n=907)$ conducted by Wu in 2003. This study found that secondary school students performed better in graph construction and graph reading than in graph interpretation and graph evaluation. Many students could not explain their statistical reasoning with graph items. Statistically significant differences were found by grade level and stream. The findings suggest that a more balanced coverage of understanding of statistical graphs required at both the primary and secondary levels.
