Final answer:
The average IQ score of a nation can change over time due to various factors such as education, socio-economic conditions, and cultural changes.
Step-by-step explanation:
The statement “True or False: The average IQ score of a nation remains constant over time” is False. The average IQ score of a nation can change over time due to various factors such as education, socio-economic conditions, and cultural changes.
For example, if a country improves its education system and provides better opportunities for its citizens, the average IQ score of that nation may increase over time. Similarly, if a country faces economic challenges or political instability, it may lead to a decline in the average IQ score.
It's important to note that IQ scores are not fixed or unchangeable and can be influenced by various factors both at an individual and national level.
