91583 Statistics 3.11: Experimental Design - 4 credits

Whoever designed Lake Wakatipu definitely studied Experimental Design

General Instructions

Why experiment with hardcore drugs when you can experiment with Experimental Design? There are plenty of reasons, but that’s not the point.

This achievement standard comprises of a three-part research project. Part 1 is planning an experiment, Part 2 is doing the experiment, and Part 3 is writing a report on the experiment.

Unlike a ‘traditional’ exam, you won’t be sitting a test at the end of your learning. Instead, you will be able to enter and leave the test as many times as you like. This will mean that you can write your Experiemental Design report over a period of time. It’s the digital equivalent of having a two week research assessment at school, where you enter and leave your classroom each day.

In the experiment, there is a big focus on reducing and measuring bias. This is why you will cover the five stages of statistical enquiry – problem, plan, data, analysis and conclusion – with a view to reducing and measuring bias in your experiment.

This assessment is based on on the NZQA 91583 achievement standard (version 2) document.


Before taking Statistics 3.11, LearnCoach recommends you should have passed some Level 2 mathematics or statistics internals or externals. If you have not done this, some of the concepts in the internal may be unfamiliar to you and you may find it a challenge. 

If you've sat a similar standard in the past that has now expired, you cannot get the same credits a second time. Check the 'Exclusions List' to see recently updated standards.
