GCSE Statistics The Normal Distribution

This resource pack has been designed specifically for the AQA GCSE Statistics specification and provides a complete lesson on the Normal Distribution, from introducing its key characteristics to applying the empirical rule (68–95–99%) in realistic contexts.

The worksheets build progressively from identifying the features of a normal distribution and comparing means and standard deviations to interpreting data, evaluating statistical statements and solving exam-style problems. Contexts include wildlife, manufacturing, health and environmental data, helping students apply statistical reasoning in meaningful real-life situations.

This resource includes:

• Progressive worksheets suitable for mixed-ability classes
• AFL strategies such as min-whiteboard questions and ‘Think, Pair, Share’ with teacher guideance in the notes section on the slides.
• Sketching and interpreting normal distributions
• Comparing means and standard deviations
• Applying the 68–95–99 empirical rule
• Exam-style reasoning and evaluation questions
• Real-world contexts including grey seal pups, oak trees, batteries, chocolate bars and healthcare
• Exit Ticket Plenary to check students understanding.

Ideal for classroom teaching and revision lessons, this resource closely reflects the style and reasoning expected in AQA GCSE Statistics examinations, with a strong emphasis on interpreting data and communicating statistical conclusions clearly.
