I took a test here in Brazil with a psychologist, I got 115, but it turns out it’s 15 points in relation to the median of Brazilians?

So if the average Brazilian has an IQ of 87, does that mean my actual IQ is only 15 points above that?

And I can’t find a good source for whether the average IQ in Brazil is 83, 87, 92… how do I know what was the sample of people the WAIS test picked?

And how can I know what would I score had I taken it in Europe or somewhere where the average is higher, thus making the 100 center point different…?

For example, let’s say you do a test in Brazil and you score 100, does that mean your actual score is 83, because 83 is the median in Brazil?

If the same person took a test in, say France, they’d score 83, since the median in France is 100, or is their score of 100 the same IQ as an average French person, but above average in Brazil?

If the Germanic tribes were running from the Huns, how come they managed to take over Rome and survive for longer?
