1. What is an “IQ”? How is it computed? If someone has an “IQ” of 100 what does this mean in terms of knowledge? IQ is the measure for intelligence. Tests are given which come up with a score that is considered the mental age, which is divided by the chronical or actual age and multiplied by 100 (Garrett, 2011). IQ scores are thought to fall on a normal curve with 100 being the mean or average. Each standard deviation away from that score (above or below) accounts for a percentage of the population that generally scores in that range. Around 34 % of the population fall between 100 and 115, the next group up is to 130 and about 13 % fall into this range with the the amounts of people in each range getting smaller and smaller. The curve works the same moving from a score of 100 down. In terms of knowledge a score of 100 means average and that there is a basic correlation between school, job performance, wages earned, and possible delinquency.

IQ is a measure of “intelligence. What are several other factors that might go into differentiating levels of intelligence? These are physiological measures. Things that might make a difference in the levels of intelligence include brain size, neural conduction and processing speed, and the efficiency the brain has in processing. When it comes to brain size larger does not mean smarter, what is important is the ratio between brain that is needed to keep your body alive and brain left for intellect (humans have a high ratio). Neural conduction and processing speed is important for humans in that they have to quickly process the stimuli and make sense of things (IQ test consider how fast you can read a question and formulate an answer-processing speed). Lastly the processing efficiency is important. The neurons in the brain are myelinated (myelin protects them) this keeps neurons working
