Investigate bivariate measurement data
You'll be investigating the relationship between two measurement variables (like height and weight, or study time and exam marks). You need to follow the statistical enquiry cycle: pose a question, collect or use existing data, display it, find patterns, fit a model if appropriate, and write up your conclusions with evidence backing every claim you make.
You investigate the bivariate data by following the enquiry cycle, creating displays, identifying features, fitting a model, and writing conclusions.
You link each step of your investigation to the real-world context and support every statement with specific statistics, data values, trends, or features from your displays.
You blend statistical and contextual knowledge throughout, reflect on your process, consider other variables that might matter, and evaluate whether your model actually fits well or discuss its limitations.
