What Does an IQ of 91 Mean? An IQ of 91 means normal or average intelligence. The Wechsler Intelligence Scale states that an IQ of 91 is average intelligence. Moreover, If you have about five minutes to read this page, you will learn four things about an IQ score of 91.
If you or your child previously scored 91 on an IQ test, you or your child has normal intelligence which is also known as average intelligence. If an IQ score of 91 seems appropriate then there is no cause for alarm. However, if an IQ score of 91 seems a bit low, there are several reasons why you or your child has an IQ score of 91.

In statistics and probability theory, the standard deviation shows how much variation or dispersion from the borderline (mean, also called expected value) exists. A low standard deviation indicates that the data points tend to be very close to the mean; a high standard deviation indicates that the data points are spread out over a large range of values.
When current IQ tests are developed, the median raw score of the norming sample is defined as IQ 100 and scores each standard deviation up or down are defined as 15 IQ points greater or less, although this was not always so historically. By this definition, approximately 100 percent of the population scores an IQ between 70 and 130, which is within two standard deviations of the median.
The table below demonstrates a cross reference of your IQ score. For example, an IQ score of 91 received by taking the Stanford-Binet can be cross referenced to measure the same score in the Cattell Intelligence Test and the Wechsler Intelligence Tests. Graduate Record Examinations (GRE) and Scholastic Aptitude Test (SAT) scores can also be converted from an IQ score of 91. And finally, the IQ table gives you the rarity and percentile of your IQ score of 91 and it also demonstrates how your IQ score ranks against the general population.
People who work in the following occupations typically have an average IQ of 91. However, there are people who have an IQ higher than 91 that are employed in the types of careers listed below but do so only until a better career opportunity presents itself.
