Investigate bivariate numerical data using the statistical enquiry cycle
You need to plan and carry out a statistics investigation using data with two numerical variables (like height and arm span, or study time and test scores). You'll work through the statistical enquiry cycle — asking a clear question, deciding what to measure, collecting and displaying your data, and then writing conclusions about what the data shows. The key is showing how your choices and findings connect back to the real-world situation you're investigating.
You work through each part of the statistical enquiry cycle, create appropriate displays, and write a conclusion about the relationship between your two variables.
You justify your choices (like why you selected certain variables or how you managed variation) and support your findings by referring to specific statistics, data values, or features you can see in your graphs.
You show deeper statistical thinking by integrating both statistics knowledge and real-world context throughout your investigation, and you reflect on your process or consider alternative explanations for what the data shows.
