What is the mean IQ score in the general population on a normal curve?
ASeventy
BOne hundred
COne hundred and thirty
DFifty
Answer & Solution
Correct answer: B. One hundred
1. IQ scores are distributed in the population in a bell-shaped normal curve.
2. The distribution is symmetrical around the central value called the mean.
3. The chapter states that the average IQ in the population is 100, irrespective of age.
4. People with IQ in the range 90-110 have normal intelligence.
5. Hence the mean IQ score is 100.
