Conduct an experiment to investigate a situation using experimental design principles
NZQA suppresses grade rates for low-cohort standards.
You'll plan and run a real experiment to answer a specific question, applying proper research design rules. You need to control what varies and what stays the same, collect and display your data properly, and draw conclusions from what you found. This is about doing statistics in action, not just theory.
You complete each step of the experimental process in order: ask a question, design and run the experiment, collect data, display it, analyse it, and draw a conclusion.
You explain why each design choice matters for your particular question, justify your statistical methods, and connect your findings directly to evidence from your experiment.
You demonstrate deep statistical and contextual understanding by reflecting on how you handled sources of variation, discussing alternative variables that could matter, and integrating statistical thinking throughout the entire investigation.
