91581 Statistics 3.9: Bivariate Data - 4 credits

Bivariate data is like Hagley Park: It feels dark & foggy, but there's sunshine on the other side.

General Instructions

This achievement standard comprises of a three-part project, using two sets of data (called bivariate data). Part 1 is plotting a graph, Part 2 is analysing the graph, and Part 3 is writing a report about the graph.

Unlike a ‘traditional’ exam, you won’t be sitting a test at the end of your learning. Instead, you will be able to work on the project 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 graphing, there is a big focus on the relationship between two sets of data. So you will look at drawing the data (on a graph), evaluating, interpreting the data, and forecasting what might happen in the future.

This assessment is based on on the NZQA 91581 achievement standard (version 2) document.


Before taking Statistics 3.9, 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.
