Investigate time series data
Investigate time series data
In this standard, you investigate a time series dataset (data that changes over time, like monthly rainfall or annual house prices). You'll follow the statistical enquiry cycle: pick a variable, display the data, spot patterns, fit a model to describe it, forecast future values, and explain your findings using statistics and context.
You follow all steps of the statistical enquiry cycle on your chosen time series, identify some key features, fit a model, and write a conclusion.
You link each step of the cycle to your data context, use statistics and specific data values to support your statements about trends and patterns, and show that your model choices make sense.
You weave statistical and contextual knowledge throughout, reflect on your method, consider other variables that might matter, evaluate whether your model is good enough, and show deeper understanding of how the model works and its limitations.
