What is the general mean IQ score?

• A. 80
• B. 90
• C. 100
• D. 110

Answer: (C)

The general mean IQ score is established as 100. This value is set as the average and serves as a benchmark for evaluating individual IQ scores. The standard deviation in most IQ test distributions is 15, meaning that most individuals will score within a range of 85 to 115, which is one standard deviation above or below the mean. This standardization is essential for interpreting scores relative to the population at large. Setting the mean at 100 allows for a clear understanding of where an individual stands in relation to the average cognitive performance within a defined population. This helps in assessing learning abilities, cognitive functioning, and potential needs in educational and therapeutic contexts.
