Another Word of the Day - psychometric

"Psychometrics is a field in which practitioners attempt to measure psychological response like emotion, intelligence, or other mental-based abilities, of individuals. An individual’s test results are then compared to an average group’s performance in these areas. A key example is the typical IQ test, which measures intelligence quotient. The test score you receive on an IQ test is compared to the body of people who have taken the test previously, and a number is assigned (the score) as your IQ number. Theoretically, a higher number IQ translates to greater intelligence."
