Statistics

Statistics is only available as GCSE but as there is no practical assessment this doesn't prove an issue for home educators. 
Both options to study are tiered, so you need to decide between foundation or higher. 
Some people use Statistics as a precursor to doing Maths, others as an extension if Maths has been sat early and they want to show Maths skills being kept up to date. It's a useful course alongside subjects such as Psychology.

The AQA GCSE in Statistics covers five sections:
* Understand the importance of the careful planning of a clear strategy for collecting, recording and processing data in order to address an identified question or hypothesis.
* Recognise the opportunities, constraints and implications for subsequent mathematical analysis involved in obtaining appropriate data through careful design of primary data collection techniques or through the use of reference sources for secondary data to ensure unbiased research.
* Generate data visualisation and understand the mathematics required to derive these visualisations.
* Calculate statistical measures to compare data.
* Use visualisation and calculation to interpret results with reference to the context of the problem, and to evaluate the validity and reliability of statistical findings.
Students are also required to be familiar with the Statistical Enquiry Cycle. It is recommended they carry out practical investigations.
=== Assessment ===

Maths Genie a free online Maths site has a small section for the Edexcel Statistics GCSE, it includes past papers, mark scheme and some topic based questions with solutions (divided into topics just for GCSE statistics and crossover topics with Edexcel Maths syllabus). https://www.mathsgenie.co.uk/statistics.html
== Which board should I choose? ==
There is little difference between the content of AQA and Edexcel. If your exam centre can accommodate either, the best strategy is to download some past/specimen exam papers to see if you prefer the style of question of one board over another. The grade boundaries in 2019 were slightly higher for AQA than for Edexcel which suggests that AQA was a slightly easier paper in 2019 but this can change year to year.
At the time of writing (Sept 2020), there seems to be more textbook resources available for Edexcel but distance learning providers are available for both AQA and Edexcel. Both boards have a textbook but there are more revision resources for Edexcel.
