✨Here are some top tips to make your revision more effective:

1. Master the Basics First 📚

Statistics builds on itself. Make sure you’re confident with:

✔️ Mean, median, mode and range
✔️ Interquartile range & standard deviation
✔️ Probability rules
✔️ Data collection methods
✔️ Interpreting graphs

When the foundations are strong, the harder questions feel much easier! 💪

 2. Practise Exam-Style Questions📝

Stats becomes clearer the more you do it.

👉 Use past papers - you will find the links on this page!
👉 Practise mark-scheme language
👉 Time yourself
👉 Check which topics you consistently drop marks on

The exam questions often follow a pattern - spotting it is a revision superpower. ⚡

3. Focus on Interpretation (Not Just Calculations)📊

Many students revise the maths but forget the “explain” questions.

Practice writing short, clear, contextual answers.
For example:
Instead of “the median is lower”, write “the median is lower, suggesting this group generally performs worse”.

Being able to justify conclusions can earn you lots of marks! 🌟

4. Know When to Use Which Method🎯

Should you use a bar chart or a histogram?
Stratified or random sampling?
Mean or median?

Create a revision page titled “When to use what” - this is gold for Paper 2 reasoning questions. 💎

5. Don’t Just Memorise - Understand🧠 

Statistics is logical. If you understand why we do something, you’ll remember it far more easily.

Use short explanations, diagrams or real-life examples to help concepts stick.

6. Use Visual Revision Tools📈

Statistics is a very visual subject - take advantage of it!

💡 Try:

• Mind maps

• Sketching graphs

• Colour-coded notes

• Summary tables of formulas

7. Apply Stats to Real Life🧪

Look at data online, in sports, news or social media polls.
Ask yourself:

• What type of data is this?

• How was it collected?

• What bias might be present?

• What could the mean/median tell me?

Real-world thinking connects everything together. 🌍

 8. Take Care of the Basics🧘

Good revision means good habits:

✔️ Break sessions into chunks
✔️ Take active notes
✔️ Sleep well before exams
✔️ Stay hydrated 💧
✔️ Believe in yourself - you’ve got this!
