Commentary:
This task was first administered in 1995. Many students in both year 4 and year 8 were successful in reading a tree diagram. Three quarters of the year 8 students got all of the answers correct. Boys and girls performed similarly, but year 4 Pasifika students had a much higher proportion of low scores than Mäori or Pakeha students. Performance in 2007 for year 4 students was markedly higher than in 1995, but there was little difference for year 8 students.
