What You Need to Know

Calculating and comparing measures of average and spread. This subtopic is part of Statistics & Probability in the Cambridge IGCSE Mathematics 0580 syllabus (both Core and Extended tiers). Understanding mean, median, mode, range is essential for achieving a strong grade in your IGCSE Maths exam.

Understanding Mean, Median, Mode, Range

Calculating and comparing measures of average and spread. In the IGCSE 0580 exam, mean, median, mode, range questions appear in both Paper 2 (Core/Extended) and Paper 4 (Extended). These questions typically test your ability to apply the method to both straightforward calculations and multi-step problems. Teacher Rig recommends mastering the fundamentals before attempting more complex variations.

Step-by-Step Method

  1. 1

    Identify the problem type

    Read the question carefully and identify that it requires mean, median, mode, range. Look for key words and given information.

  2. 2

    Write down the relevant formula or rule

    State the formula or method you will use for mean, median, mode, range. This earns you a method mark.

  3. 3

    Substitute known values

    Replace the variables in the formula with the values given in the question. Show this step clearly.

  4. 4

    Solve and simplify

    Carry out the calculation step by step. Show all working to earn method marks even if your final answer is wrong.

  5. 5

    Check your answer

    Verify your answer makes sense in context. Check units and significant figures as required.
