Average IQs are 100.
The average IQ is 100, with two-thirds of the population having IQs between 85 and 115, and 95% of the population having IQs between 70 and 130.
IQ follows a normal distribution (bell curve) around the mean, usually 100. Since the normal distribution is horizontally aymptotic, technically a possibility exists for any IQ score. Therefore the concept of IQ is not like a test score even though IQs have to be obtained by taking multiple tests.
The highest IQ ever estimated was the 300 IQ of William James Sidis. The highest IQ of a person alive today and recordedis the 228 IQ of Marilyn vos Savant. Both of these IQs were ratio IQs, meaning they were calculated by figuring out the person's "mental age" based on how many questions they answered and then using the formula Mental age/chronological age * 100. IQs are no longer calculated this way.
It has no unit; it is just a number, which is based on a normal distribution with mean 100 and standard deviation 15. The "average" person has an IQ of 100. There is a standard error associated with calculating IQs of a 95% chance that the actual IQ is within the range of the given IQ ± 4; which means that someone with an IQ of 102 could actually have less of whatever it is the IQ tests measure than someone with an IQ of 100.
There are many smart (and stupid) people, men and women, from every race in the world.
Although there is no very reliable study of the average IQ of lawyers, most estimates place it between 115 and 130, in the "high normal" to "superior" range. Of course, since that's the average, that means there are lawyers with IQs below that and also lawyers with IQs above that.
The average IQ is 100, with two-thirds of the population having IQs between 85 and 115, and 95% of the population having IQs between 70 and 130.

Yes. IQs are normalized by age. The average IQ is 100 with a standard deviation of 15 by definition. So, a 113 falls right at the top of the average range.
The IQs of a large enough population can be modeled with a Normal Distribution
It is very normal. Don't worry about being different. Answer 113 is actually "high-average". To give you some idea what that means in the context of large groups of people with similar IQs, the average college student has an IQ of approximately 115. Roughly half of college students have IQs equal to or higher than 115; roughly half have IQs equal to or lower than 115. If a prediction were to be made based only on IQ, a young woman with an IQ of 113 should be very comfortable with college-level academic studies.
An IQ of 149 is excellent for any age -- and is considered to be in the high range of normal. Correct:The average IQ of the population as a whole is, by definition, 100. IQs range from 0 to above 200, and among children, to above 250. However, about 50% of the population have IQs between 89 and 111, and about 80% of the population have IQs ranging between 80 and 120, with 10% lying below 80, and 10% falling above 120.

Usually in elementary school, people who are believed to have either far above-average, or below-average IQs are invited to take one. Otherwise contact a local Mensa chapter, they will be happy to test you.
IQs cannot be applied to animals.
