Subgroup Analysis [Click on charts to enlarge] : |
Commentary: |
Many students weighed Parcel C to the nearest 100 grams (600gm), rather than
more precisely (Parcel C actually weighed 555gm). Year 4 students scored
slightly higher in 2009 than 2005, and year 8 students slightly lower. On
average, year 4 Mäori and Pasifika students scored substantially lower
than Pakeha students. |
