Prerequisite Knowledge
Statistics S1 Unit
Knowledge of the specification content of Module C1 and C2 are assumed, and candidates may be required to demonstrate such knowledge in answering questions in Unit S1.
The specification content of this module include some items that are part of GCSE Mathematics at Intermediate Tier (e.g. mean, median, mode, interquartile range, stem-and-leaf diagrams, box-and-whisker plots). These are included for completeness; where any such items are involved in examination questions, the main focus will be on interpretation rather than elementary calculations.
The specification content of this module is to be understood in the context of real-life situations, and examination questions may ask for comment and interpretation, including where appropriate, cross-checking between a model and reality.
Candidates should know the following formulae, none of which are included in the List of Formulae made available for use in the examination.

Standard Deviation: or
Statistics S2 Unit
Knowledge of the specification content of Module C1 to C4 and S1 are assumed, and candidates may be required to demonstrate such knowledge in answering questions in Unit S2.
No other prerequisite knowledge is required.
Statistics S3 Unit
Knowledge of the specification content of Module C1 to C4, S1 and S2 are assumed, and candidates may be required to demonstrate such knowledge in answering questions in Unit S3.
Candidates should know the following formulae, none of which are included in the List of Formulae made available for use in the examination.
Expectation Algebra
Statistics S4 Unit
Knowledge of the specification content of Module C1 to C4, S1 to S3 are assumed, and candidates may be required to demonstrate such knowledge in answering questions in Unit S4.
Candidates will need to be familiar with, at least, the section on using the first few terms of the Maclaurin series from FP2 and, in particular, be familiar with the series expansion of ex
