3.9B Sub-species (NZQA)

An internal assessment resource provided by NZQA to support internal assessment of the Achievement Standard 91581.
This activity requires students to investigate possible relationships between variables relating to head measurements for Hector’s dolphins. They then need to decide if the classification of North Island dolphins as a new subspecies from South Island dolphins can be supported by the findings of the investigation.
