NZC Level 8, NCEA Level 3: Statistics and Probability

3.11 Conduct an experiment to investigate a situation using experimental design principles

Internal 4 credits

This standard is derived from Achievement Objective S8.1 Carry out investigations of phenomena, using the statistical enquiry cycle, and Achievement Objective S8.2b Make inferences from surveys or experiments and use methods such as randomisation.

Students should be able to:

    • Pose an investigative question about a given experimental situation
    • Conduct the experiment
    • Select and use appropriate displays and summary statistics
    • Make appropriate formal statistical inferences
    • Communicate findings in a conclusion

This standard requires students to use random allocation to treatment groups and randomisation tests to assess the strength of evidence for the causal inference. Computer use is essential.
