Identifying the IQ Score Threshold for Average Intelligence- Which Deviation Indicates the Norm-

Which of the following deviation IQ scores indicates average intelligence? This is a question that often arises when discussing the concept of intelligence quotient (IQ) and its application in various fields. The IQ score is a measure of a person’s cognitive abilities relative to the general population. In this article, we will explore the different deviation IQ scores and determine which one represents average intelligence.

The IQ scale is based on a standard deviation of 15 points, with a mean of 100. This means that a person with an IQ of 100 is considered to have average intelligence. However, the deviation IQ scores provide information about how an individual’s IQ compares to the average. In other words, a deviation IQ score of 0 indicates average intelligence, while scores above or below 0 indicate above-average or below-average intelligence, respectively.

Let’s take a closer look at the deviation IQ scores and their implications:

1. IQ Score of 0: This is the deviation IQ score that indicates average intelligence. A person with an IQ of 100 has a deviation score of 0, meaning their cognitive abilities are on par with the general population.

2. IQ Score of +1: This deviation IQ score represents slightly above-average intelligence. A person with an IQ of 101 has a deviation score of +1, indicating that their cognitive abilities are slightly better than the average.

3. IQ Score of -1: This deviation IQ score indicates slightly below-average intelligence. A person with an IQ of 99 has a deviation score of -1, meaning their cognitive abilities are slightly below the average.

4. IQ Score of +2: This deviation IQ score represents above-average intelligence. A person with an IQ of 102 has a deviation score of +2, indicating that their cognitive abilities are significantly better than the average.

5. IQ Score of -2: This deviation IQ score indicates below-average intelligence. A person with an IQ of 98 has a deviation score of -2, meaning their cognitive abilities are significantly below the average.

In conclusion, the deviation IQ score of 0 indicates average intelligence. It is important to note that the IQ score is just one measure of cognitive abilities and should not be used to define a person’s worth or potential. Intelligence is a multifaceted concept, and various factors contribute to an individual’s overall cognitive and intellectual capabilities.
