What’s the Average IQ Score on an IQ Scale

IQ Test Score

IQ, which stands for “intelligence quotient,” is a test that tells how smart you are. This number shows how well you did on a test compared to other people your age.
Anything below 70 is a low IQ score. Someone may have an intellectual disability if they get a low number or other signs. If your IQ score is over 140, you are a genius.2 Even though there is no proof that he was ever tested, Albert Einstein is thought to have gotten a score of around 160.

Experts say that IQ alone isn’t always a sign of success in life, but it can help predict things like how well someone will do in school. People with normal IQs may do well in life while people with very high IQs may not.

What Does IQ Stand For?

People take IQ tests to see how smart they are and get a number that tells them how their results compare to those of other people their age. IQ measures many mental skills, such as the ability to think and reason verbally, see clearly, be aware of your surroundings, process information quickly, and spot patterns.

What is the Average IQ Score based on an IQ scale?

How to measure intelligence has been a hot topic and a difficult one in psychology and education for a long time. One type of psychology test that is used a lot today is the intelligence test. Since the first IQ test, people have tried to put IQ into groups.

Before you can understand what an average IQ score is and what it means, you need to know how to measure IQ. Different test companies use different ways to score, but for many modern IQ tests, the average (or mean) score is set at 100 with a standard deviation of 15, which makes the numbers fit into a normal distribution curve.

A score of 100 on many tests means that the person has an average IQ.
68% of the numbers are within one standard deviation of the mean, which means they are between 85 and 115. That means that almost 70% of people get a score that is within 15 points of the average.

About 95% of results are within two standard deviations, or between 70 and 130. Individuals with IQs below or above those ranges don’t represent a large part of the population. This means that very few people have IQs below 70 or above 130.

Scores below 70 could mean that someone has a developmental or learning disability, while scores above 130 could mean that someone is talented.

What is the average IQ score by age

A study says that the average IQ for each age group can be understood in this way:

  • The average number for 16–17-year-olds is 108. This means they are smart enough.
  • The average IQ number for adults between the ages of 18 and 19 is 105. This also means they are smart enough.
  • Between the ages of 20 and 24, the average number is 99, which also means that a person is smart enough.
  • When it comes to people between the ages of 24 and 34, the average number is 97.  This still means they are smart enough.
  • For people over that age, the scores start to go up again. For instance, the average number for people aged 35 to 44 is thought to be 101. This is still in the normal or average range of intelligence.
  • The average IQ number for people 45 to 54 years old is 106. This is on the normal or average range for intelligence.
  • On the IQ scale, people between the ages of 55 and 64 get the best average score for people younger than 64. They get 109.
  • The average IQ score for people aged 65 to 69 is 114. This means they are smarter than average. If you test someone between the ages of 70 and 74, they get an even higher average score of 119.

How IQ Is Measured

In the past, there have been two ways to score IQ tests. For the first way, the mental age of a person was divided by their actual age and then multiplied by 100. When using the other ways, scores are compared to those of people the same age as the person.

Psychometricians use a process called “standardization” in this method to make it possible to compare IQ numbers and figure out what they mean. One way to do this is to give the test to a group of people. They are representative of the whole. And then use their scores to set standards, or norms, against which all other scores can be judged.

Since 100 is the middle score, experts can quickly compare each test score to the middle score to see where these numbers fall on the normal distribution. Half of the scores are above or below this middle point. They are both 100, which is the mean of all IQ tests. Different publishers have different ways of classifying books, but most of them use a pretty standard method.

Nationality Differences in Average IQ Scores

IQ scores may be different between countries, according to research that looks at cognitive skill across nations. There haven’t been many studies like this yet, but some have been done by estimating the average IQ for different countries. These kinds of differences might have a lot to do with things in the surroundings, like socioeconomic factors, life expectancy, literacy rates, and educational rates.

Researchers Richard Lynn and Tatu Vanhanen found that the average IQ in Equatorial Guinea was only 59. The average IQ in Hong Kong was 108. The United States had an average group IQ of 98, the United Kingdom had an average of 100, and Italy had an average of 102.3

What Does It Mean to Have an Average IQ?

There are some broad things about your normal IQ score, but keep these things in mind:

It means your ability to think and solve problems is average. Many experts say that IQ tests don’t tell the whole story when it comes to figuring out how smart you are or how well you can solve problems.

It’s possible that your average IQ number doesn’t fully show what you can do. Some things they don’t test are strengths and weaknesses in real life.

Even if your IQ is normal, you could be a great musician, artist, singer, or mechanic. The psychologist Howard Gardner came up with the idea of multiple intelligences to fix what he saw as a flaw in the way most people thought about IQ. IQ scores don’t always stay the same. IQ scores change over time. One study looked at the IQs of teens when they were just starting to become teenagers and then again four years later. Scores changed by up to 20 points over the course of four years, according to the findings.

There are some experts who say that EQ maybe even more important than IQ.

IQ tests also don’t measure how interested you are in the world around you or how well you can understand and control your feelings. EQ, or emotional intelligence, is often thought to be even more important than IQ by some experts, such as author Daniel Goleman.

Researchers have also found that having a high IQ can help people in many parts of their lives. However, it is not a guarantee that they will be successful.
