A person's raw score from an IQ test, for instance, can be compared to the raw scores of others in his age group. The average IQ for most age groups is usually between 90 and 110. Personality tests might also be created by psychometricians. As their name suggests, these types of tests help measure and reveal certain parts of a person's personality. Questions on these types of tests usually ask about certain situations, and how a person feels about them or would handle them.
