Best Answer

Nearly everything in nature can be measured on a bell curve. It is a natural tendancy that math tries to explain with the bell curve. The result of all our genes working together produces an individual. Some genes are more favorable to a high intelligence than others. Therefore the most common result is the apex of the curve, and the less common results have lower probability.

What is a bell curve?

A bell curve is a symmetrical bell-shaped graph curve that represents the arrangement of values, how often something occurs, or probability of occurance of a set of data. It slopes downward from a point in the middle corresponding to the average also called mean value, or the maximum probability. Gather all the results of an IQ test and make a graph of them, would create a bell curve with average IQ being the mean value. The more results or values, the better the bell curve. It can be made with a line graph or a bar graph.

What does 111 IQ mean?

IQ is a "Normally Distributed random variable" meaning that it follows a bell curve. This curve is centred on 100, meaning that 100 is the average value for all people. The standard deviation is 15, meaning that 95% of the population is meant to be within 70-130 for their IQ. 111, therefore, is a slightly-above-average IQ test, however, IQ tests are subject to error, and depending on the questions, you could get a different score next time.
