Taking your question literally... yes, they could both have the same IQ.
If you're asking if a four-year-old could be as smart as a 25-year-old, only if the latter is really, really stupid.
Yes. An IQ over 120 is considered great for anyone, so for a four year old, it's fantastic.
110
A score of 107 is a little above the average IQ score of 100.
100 is the average for any age group.
115 is a good score at any age. It's "high average". The average IQ is 100, by definition. Only 25% of the population has an IQ higher than 110.
The average score for a person of any age is 100 that includes 25 year olds, your mum, your dad, and grandparents, everyone.
198 a good iq for a 10 year old
Average IQ scores don't change between age groups. The average IQ for a 10-year-old and the average IQ for a 40-year-old, as well as a 30-year-old and so on, is 100. It is the average IQ score for all age groups.
Her IQ i still 135 because all IQ tests are standerised
It is a very good IQ and above average. 100, plus or minus 10 points, is considered average.
Yea! The average IQ for a 5 year old is about 100!
An IQ of 124 is a good IQ.
