Question

Which of the following is true of IQ?

1) The Flynn effect describes how IQ scores are continuously rising–specifically 5 points every 3 years.
2) IQ is standardized with an average of 100, meaning your IQ score is solely based on your performance.
3) IQ is standardized with an average of 100, meaning your IQ score is relative to the scores of others.
4) The Flynn effect describes how IQ scores are continuously rising–specifically 15 points every 3 years.

Answer 1

IQ is standardized with an average of 100, meaning your IQ score is relative to the scores of others. The Flynn effect describes how IQ scores have been continuously rising over time.

Step-by-step explanation:

IQ is standardized with an average of 100, meaning your IQ score is relative to the scores of others. This is because IQ scores are interpreted using standard deviations, which describe how data are dispersed in a population. On most IQ tests, one standard deviation is 15 points, so scores between 85 and 115 are considered average. Scores above 130 are considered superior.

The Flynn effect, named after James Flynn, describes how IQ scores have been continuously rising over time. However, the exact increase is not 5 points every 3 years as mentioned in option 1, but rather varies based on the specific population and time period.
