## Summary

This statistics unit builds on Unit 14: Data - and begins with a well-paced revision of the prior knowledge required for this unit. Types of data, including primary and secondary data, are considered and the collection of these explored. Sampling of data is examined along with understanding bias and how to avoid it to produce representative samples from a population. Times series are studied next; constructing tables for data and producing and interpreting appropriate graphs of this data. The unit is completed by a thorough consideration of scatter graphs in a real-life context; interpreting the line of best fit and using it to predict values where appropriate, understanding correlation and its relationship to causation.
