Median: Your Questions Answered
These are the questions people ask most often about median. Each answer is short; follow the links for the full detail.
What does a median calculation tell me?
Finds the middle value of a list.
What is the formula?
Sort the values; take the middle one (or the average of the two middle values).
What do I need to enter?
Numbers (separated by commas).
Can I use any units?
Yes, as long as every input uses the same unit. The answer will be in that unit (squared for areas, cubed for volumes).
Can you show an example?
For example, with these inputs:
- Numbers (separated by commas): 12, 15, 9, 22, 15, 30
the calculator returns:
- Median: 15
Any tips?
- Keep units consistent: convert everything to the same unit before calculating.
- Write down the formula before plugging numbers in; it prevents mixing up variables.
- Estimate the answer roughly first so you can spot a result that is clearly wrong.
Background
Rounding is a common source of small errors. Keep full precision during intermediate steps and round only the final answer to the number of decimal places or significant figures the question asks for.
These calculations appear throughout the Singapore syllabus, from primary school percentages and fractions to secondary school algebra and geometry. Understanding the formula makes problem sums easier because you can recognise which quantity is missing.
Calculators are best used to check working rather than replace it, especially for exams where method marks count. Work the problem by hand first, then confirm with the calculator.
