What Is the Normal Range for IQ?

An IQ score above 140 indicates genius or nearly genius. Einstein’s estimated IQ scores range from 205 to 225 by different measures.

The intelligence quotient or IQ is a standardized method to know the mental ability of a person, usually against a peer group.

IQ scores between 90 and 109 indicate average intelligence. Individual adults usually score somewhere between 70-130, with 100 being the theoretical average.

If you score above 130, your score is higher than the average population, and below 70 would be lower than the average population.

What is the average IQ for each age group?

According to research, the average IQ for each age group is as follows:

• The average score for 16-17 year-olds is 108, which denotes average intelligence.
• For adults between 18 and 19 years of age, the average IQ score is 105, which also denotes average intelligence.
• The average score for people between 20 and 24 years of age is 99, which also denotes average intelligence.
• For people between 24 and 34 years of age, the average score is slightly lower at 97, which still denotes average intelligence.
• The scores begin to rise again after that age, among older adults. For example, the average score for people between 35 and 44 years of age is estimated to be 101, still within the average intelligence scale.
• For people between the ages of 45 and 54, the average IQ score goes up to 106 within the average intelligence scale.
• The highest average score for people under 64 years of age is attained by those people between the ages of 55 and 64, who get 109 on the IQ scale.
• People between 65 and 69 years of age have an average IQ score of 114, which puts them in the superior intelligence or above-average end of the scale. But people between 70 and 74 years who are tested for IQ get an even higher average score of 119.

Is a 120 IQ good?

An IQ score of 120 is considered good, indicating superior or above-average intelligence.

What is a good IQ score?

A score of 100 is considered the average IQ, and anything above that is above-average intelligence for a person’s age. IQ is based on a statistical calculation comparing a person’s results to those of other people their age.

IQ tests generally focus on a person’s:

• Memory
• Mathematical skills
• Reasoning ability
• Processing speed
• Language, including vocabulary
• Visuospatial processing (the ability to perceive, analyze, recall, and manipulate images oriented in space and keep track of the location of moving objects)

QUESTION

What is the meaning of IQ?

IQ stands for intelligence quotient, a popular tool for job placement and educational services, especially for placing children in an appropriate educational setting.

• An IQ score is a numerical representation of an individual’s intelligence within a normalized scale of results.
• Most modern tests are adjusted so that the mean score is 100.
• IQ score is an average of multiple scores.

Intelligence tests assess various categories, such as working memory, verbal comprehension, processing speed, and perceptual reasoning. These individual scores are combined to create an overall IQ. IQ scores often include verbal and performance scales. People are usually stronger in one area than the other, so combining these scores helps identify intelligence.

What are the uses of an IQ test?

An IQ test may be used for:

• Assessing a person’s eligibility for a job
• Educational assessment
• Diagnosis of intellectual disabilities
• Psychological research purposes
• Evaluating a person’s cognitive abilities, including attention, memory, mathematical skills, problem-solving skills, and response time

What factors influence a person’s IQ?

Several factors can influence a person’s IQ, such as:

• Age – IQ increases with age
• Educational background
• Cultural practices and beliefs
• General health, including any underlying health conditions
• Environment
• Genetics
• Musical training
• Brain anatomy

Although IQ is commonly used to measure intelligence, it has earned significant disrepute over the years.

• Researchers argue that IQ may not comprehensively classify a person as more or less intelligent, as intelligence encompasses various aspects.
• People with a higher IQ do not necessarily perform well under different circumstances, including different levels of stress.
• Classifying people based on IQ can result in prejudice against those with a lower IQ, leading to the formation of groups based on IQ levels.

Moreover, IQ does not measure the abilities necessary for making good judgments in real-life situations. Intelligence goes beyond IQ and encompasses a person’s work productivity, adaptability to life situations, and emotional well-being.

What are the differences between aptitude tests and IQ tests?

The differences between aptitude tests and intelligence quotient (IQ) tests are as follows:

Aptitude tests

Most aptitude tests assess specific skills; cognitive aptitude tests measure a broad range of abilities and provide individual scores for each ability. Cognitive aptitude testing can be done through standardized tests or game-based assessments.

• These tests measure specific areas of intelligence.
• Age is not a factor.
• There is a score for each category.
• These tests are highly predictive of job performance.
• The most common use is pre-employment testing.

IQ tests

IQ tests are typically standardized tests that cover a wide range of questions, including logical, visual, spatial, classification, analogical, and pattern-driven questions. IQ is determined by the deviation between the test score and the average test score of people of the same age. IQ is considered a rough metric for general intelligence.

• These tests measure general intelligence.
• Age is used to determine IQ scores.
• One general score is determined.
• These are moderately predictive of job performance.
• The most common uses are research and education.
