Grade 11 Core Mathematics Statistics and Probability Notes

Revise Statistics and Probability with a focused study outline for Core Mathematics. Use the explanation, activity and self-check below to organise your revision and identify areas that need further practice.

Topic overview

Statistics describes data; probability models uncertainty. The mean, median and mode answer different questions about a dataset. Probabilities must refer to a clearly specified event and sample space.

Try this revision activity

Find the mean and median of 2, 3, 3, 4 and 18. Explain why the two measures give different impressions.

Begin with a short plan before writing a full response. Identify what the question asks you to explain, calculate, compare or evaluate. Use a diagram, a worked calculation or a specific example where it makes the reasoning clearer.

Check your understanding

Justify the selected measure or probability model using the context of the question.

Compare your response with your class notes and the guidance from your teacher. If you find a difference, identify the exact point of disagreement and work through it. Make a short correction note so you can revisit the issue later.

Build your revision record

1. Record the important terms and explain each in context.
2. Summarise the main relationships using a diagram or a short outline.
3. Complete an activity without looking at the explanation.
4. Check your reasoning and correct errors clearly.
5. Return to the topic after a gap and test what you remember.
