Why learn about averages and range?

To find an average of a set of figures, add them all up and divide by the number of figures.

Quick tips for tutors

Averages and range includes:

  • Explanation of range and the different types of average.
  • Worked examples of the process for calculating the arithmetic mean, median and mode.
  • Activities to practise extracting information from tables, charts and diagrams to calculate range and average. 

What do the levels mean?

Skillswise uses the levels of the National Qualifications Framework, which start at Entry 1, 2 and 3 and then go on to Level 1 and Level 2.

  • Entry 3 covers the basic concepts and is a good preparation for starting a Level 1 course.
  • Level 1 is roughly equivalent to a GCSE D-G grade in England, Northern Ireland and Wales, and a Foundation level at Standard Grade in Scotland. A useful qualification for many jobs.
