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!
