Question

4. Juanita has taken two IQ test in her life. When she was 30 she scored 130 on her first IQ test. She then took another test when she turned 40. What is MOST likely to be true of Juanita's score on the second test

The score on the second test should be higher as 10 improves with age
The score on the second test should be close to 130 as IQ is a steady measurement
The score on the second test should be lower as IQ peaks at age 35 and then decreases
The score on the second test should be 10 points lower due to Juanita's mental age.

Answer 1

It is most likely that the score on the second test should be close to 130 as IQ is a steady measurement. Intelligence quotient (IQ) is a measure of a person's cognitive ability and is typically considered to be a stable trait that does not change significantly over time. While some research has suggested that certain aspects of cognitive ability may improve with age, the overall IQ score is generally considered to be a consistent measure of cognitive ability. Therefore, it is unlikely that Juanita's score on the second test would be significantly different from her score on the first test.

Sorry if I answered it late :D
