- Using the class width instead of the midpoint

Yes. Frequency Tables & Grouped Data appears at both Foundation and Higher tier, though Higher papers take it further.
What should I know before starting Frequency Tables & Grouped Data?
It builds on Averages. If those feel shaky, practise them first — Frequency Tables & Grouped Data questions assume them.
What is the most common mistake in Frequency Tables & Grouped Data?
Dividing by the number of rows instead of TOTAL FREQUENCY.
Which exam boards cover Frequency Tables & Grouped Data?
All four we support — AQA, Edexcel, OCR and Eduqas. GCSE Maths subject content is set by the DfE, so the topic is common to every board; what changes is the paper structure and the grade boundaries.
