Correlation versus causation

What you need to know

Understand the fundamental principle that statistical correlation does not necessarily imply direct causation.
Explain how multiple contextual factors may interact concurrently to artificially produce strong apparent correlations.
Identify and analyse incidents of spurious correlation, understanding that simultaneous variation across multiple variables may largely stem from a broader, unplotted background factor (e.g., overall population size impacting both car ownership and total births).
