This is known as a standardised score and it often corresponds to a ‘normed’ score. The Sten scale ranges from 1-10 along a normal distribution. Individuals with a sten score of 5.5 are said to be at the 50th percentile which means they have done better (or worse) than 50% of people who have taken that assessment previously (norm group).This scale is often used for personality assessments as it makes it easier to feedback using behavioural descriptors which are attached to each value.
