What is average IQ by age?

Question

i kno a lotta u say 100 4 all but i dont think thats rite...

Answer 1

for all ages (as legitimate IQ tests are normed for ages):

70-79 Borderline

80-89 Low Average

90-109 Average

110-119 High Average

120-129 Superior

The score of "100" is considered to be at the 50th percentile, meaning 50% of scores fall below and 50% of scores fall above.

Spelling is not your forte - be glad IQ tests do not examine that area.
