2. 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)

3. 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)
This indicates that your intelligence is ‘above average’
An IQ of 100, means that ‘mental age’ = ‘chronological age’

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

5. 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

6. 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 in the text book (you will need this for the exam!!!)

7. 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)
