ab: 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.
