a numerical scale unit derived by dividing an individual's results in an intelligence test by the average score for other people of the same age. Thus, a 4-year-old child who scored 150 on an IQ test would have a mental age of 6 (the age-appropriate average score is 100; therefore, MA = (150/100) × 4 = 6).
Mental age is the age level of an individual's mental ability. It is based on the age in which it takes an average individual to reach that same level of mental attainment. Mental age is usually measured by standardized intelligence tests.
Expert-Verified Answer
Given a 14 year old child has a mental age of 16.
Hence, the required mental age for a group of 12-year children is 9.6 years or more and 16.8 years or less.
Mental Age is based on intellectual development. Chronological Age is the number of years a person has lived. When A child of 16 years scores 75, his mental age will be: 75 = MA / 16 x 100.
Depressed teenagers may be at risk of suicide, even if signs and symptoms don't appear to be severe. If you're a teen and you think you may be depressed — or you have a friend who may be depressed — don't wait to get help. Talk to a health care provider such as your doctor or school nurse.

On many tests, a score of 100 is considered the average IQ. Sixty-eight percent of scores fall within one standard deviation of the mean (that is, between 85 and 115). That means that nearly 70% of all people score within plus or minus 15 points of the average score.
Thinking and Learning
Children in this age group might: Have more ability for complex thought. Be better able to express feelings through talking. Develop a stronger sense of right and wrong.
They have found that teenagers are so moody largely because brain cell development occurs at different rates in different brain regions. During early adolescence, there are rapid decreases in gray matter and increases in white matter in the limbic system (hypothalamus and amygdala)3.
17-Year-Old Language and Cognitive Milestones
By age 17, most teens have good organizational skills. As a result, they are able to successfully juggle extracurricular activities, part-time jobs, and school work. But even though many 17-year-olds think they are adults, their brains still have not yet fully developed.
The fixed average is 100 and the normal range is between 85 and 115. This is a standard currently used and is used in the Stanford-Binet test as well.
What is the difference between mental age and IQ? Mental age and IQ are related, but not the same thing. Mental age is a measure of a person's intellectual development compared to their peers, while IQ is a score based on standardized tests designed to measure intelligence.
IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120.
FAQs (Frequently Asked Questions) When did Elon Musk take an IQ test? The Tesla CEO is estimated to have an IQ score of around 155.
An IQ of 120, therefore, implies that the testee is brighter than about 91% of the population, while 130 puts a person ahead of 98% of people.
His performance beats those of physicists Stephen Hawking and Albert Einstein, who were both estimated to have IQs around 160.
To answer this question, 4 categories of gifted students are compared, consisting of above-average intelligent students (IQ between 110–119), mildly gifted students (IQ between 120 – 129), moderately gifted students (IQ between 130 – 144), and highly gifted students (IQ above 144) with respect to underachievement and ...
Because the variation in scores for different age groups taking graded tests increases roughly in proportion to the increase in age, mental ages cannot be used accurately to compare the basic ability of children of different chronological ages.
Changes in the Aging Brain
As a person gets older, changes occur in all parts of the body, including the brain. Certain parts of the brain shrink, especially those important to learning and other complex mental activities. In certain brain regions, communication between neurons (nerve cells) may not be as effective.
It's calculated by subtracting the year you were born from the current year. But your mental age, aka intellectual age, is determined by your attitude, behavior, and intelligence. The concept of mental age was first introduced by Alfred Binet who developed the first mental age test in 1905.
