IQ = INTELLIGENCE QUOTIENT IQ & IT’S CALCULATION IQ = INTELLIGENCE QUOTIENT A numerical score on an intelligence test To work out that number we use the ‘mental age’ (the score they get on the actual test) and a person’s ‘chronological age’ IQ = MA (Mental Age) x 100 CA (Chronological Age) 1

IQ = INTELLIGENCE QUOTIENT IQ & IT’S CALCULATION IQ = INTELLIGENCE QUOTIENT Example: Your chronological age is 14 years and 6 months (174 months) You achieved a mental age of 16 years and 6 months (198 months) IQ = 198 (MA) x 100 = 114 174 (CA) 1 This indicates that your intelligence is ‘above average’ An IQ of 100, means that ‘mental age’ = ‘chronological age’

IQ & IT’S CALCULATION BUT STOP!!!!! When testing adults we don’t use this method anymore to work out IQ

IQ & IT’S CALCULATION Instead for tests like Stanford-Binet and Wechsler we compare the test-taker’s scores against others of the same age

FREQUENCY DISTRIBUTION This is known as a normal distribution (bell-shaped pattern) It is a way of showing the frequency of quantitative data To understand Frequency Distributions & Central Tendency refer to Pages 305-309 in the text book (you will need this for the exam!!!)

DOES IQ = INTELLIGENCE An IQ score does not show ‘amount’ of intelligence Rather it is simply a score which places people relative to others of their age…on their performance on a test! We then know how many people are the same IQ (eg. frequency distribution)
