Yeah or spot that for a 0-10 range the mean is 6.75 and the median is 8.5
and think 'hmm I've got some odd data need the bottom end of the range I
need to look at'. It's like the old chestnut of 4 people in a room earn
£25,000 each and in walks someone who earns that combined. The average
jumps to £40k while the median stays at £25k, which is the more accurate
figure?
