GCSE Statistics – Foundation Edexcel for May/June examinations.

What is statistics?

Statistics is the practice of collecting, processing and analysing data.

Statistical analysis can be used to create mathematical models of situations such as weather patterns, global financial markets or the behaviour of humans or animals.
