Year 8
Commentary:
Almost half of the year 8 students were quite successful at making a pie graph from data presented in a table. The most common problem came in properly labelling their graphs. There was a slight decline in performance from 2003. Mäori and Pasifika students performed similarly, but markedly less well than Pakeha students, on average.
