What mean, median and mode means

You learn how to find a typical value from a set of numbers using the total, the middle value, or the most frequent value. This helps you read data quickly and answer exam questions on simple statistics with confidence.

What you will practise

  • Add all the values in a data set correctly.
  • Divide the total by the number of values to find the average.
  • Arrange numbers in order and pick the middle value.
  • Spot the number that appears most often in a list.

Before you start

You should be able to add, divide, and order whole numbers. You also need to count how many values are in a data set.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Find the mean of 4, 6, 8, 10, 12.

Answer: 8

Working: Sum = 40, divided by 5 values = 8.

Common mistakes to avoid

  • Forgetting to arrange numbers before finding the middle value.
  • Using the middle number when there are two middle values and not averaging them.
  • Dividing by the wrong number after adding the data values.
  • Choosing a repeated number that is not the most frequent one.
