Use statistical methods to make a formal inference
This standard asks you to work through the full statistical enquiry cycle to answer a real question using data that's already been collected. You'll need to choose appropriate graphs and summaries, understand how sample variation works, and then make a formal statistical conclusion backed up by evidence. It's about actually *doing* statistics to investigate something, not just calculating numbers.
You work through the statistical enquiry cycle, select appropriate methods, make a formal inference, and show you've understood sampling variability and the role of sample statistics.
You link each part of your statistical analysis explicitly to the context or population you're investigating, and reference specific data values, statistics, or features of your graphs to support what you claim.
You weave statistical knowledge and contextual understanding together throughout your enquiry, reflect on your process and its limitations, and consider other possible explanations for what you've found.
