Understanding the Three Kinds of Average in Maths

Part of the Numeracy Tests For Dummies Cheat Sheet (UK Edition)

There are three kinds of average in maths that you may need to know about in your numeracy test. Here’s a quick reminder for you:

  • The mode is the most popular category – the one that shows up most often.

  • The median is the value of the middle data point – half the data are bigger than this, and half the data smaller.

  • The mean is what you normally mean by average (add everything up and divide by how many things there are). It’s the meanest thing they can ask!
