Mean, Mode and Median

Most students don't realise that when they say "average" there are in fact three different ways of measuring the "average".

They are 
  • the Mode - the most common number in the data
  • the Median - the number in the middle of the data when it is in order
  • the Mean - the sum of the data divided  by the number of pieces of data
These three terms are all called "Measures of Central Tendency".

Try the Project Maths quiz on mean and adding a constant to the data.
