Self Improvement Made Easy

A brief history on Intelligence Quotient. The earliest and foremost IQ test was intended to identify children who required unique help in dealing and coping with their school and studies. The first IQ test was ascribed to Alfred Binet (French psychologist) in the year 1905 who also published the initial modern intelligence test. A modification of the primary IQ tests was published in 1916 in Stanford University by Lewis M. Terman. In 1936, David Wechsler published the foremost IQ test and was clearly considered for the adult population. This scale was named the Wechsler Adult Intelligence Scale, or also known as WAIS.

Ever since the publication of the Wechsler Adult Intelligence Scale, the Wechsler Intelligence Scale for Children was further developed then coined WISC—which is still in the general usage. Wechsler’s scales divided the performance and verbal IQ scales. This made it less dependent on general verbal aptitude than the early versions of the Stanford scale. Some remarkable and interesting good IQ range guide:

o IQ ranges from 0 to 250 for kids
o IQ ranges from 0 to 200 for adults.
o Individuals with low IQ below 75 (around 5% of the population) are typically difficult to train.
o 10% of the population has below 80 IQ So what’s a good IQ range? It is measured as IQ=(mental age/chronological age)*100.

It means that the average population IQ must be 100 (1/1*100). Some IQ truths and myths:

o Breastfeeding has very little to do with an individual’s IQ levels.
o Several researches have united on the scientific observation that the brain frontal lobes are very crucial and vital for one’s intellect.
o Generally, males and females have similar average Intelligence Quotient. Nevertheless, there are more males with low and high IQ levels than women.
o Mental age which is the divisor of the Intelligence Quotient equation ends at age 16.
o Modern researches and studies using MRI images have revealed that the size of the brain has a correlation with IQ.
o Good Intelligence Quotient range and its connection to race have been controversial.
o Studies have exposed that there’s an association between an individual’s structure of the cortex and the IQ scores.

The IQ levels-an Intelligence Quotient level of 130 of a 10 year old child ((13/10)*100=130) means that his or her mental age is 13. Hence, the current version of the Intelligence Quotient is a mathematical conversion of the rank which is the principal result of an IQ test. Definition of IQ tests could aid in identifying particular criteria for the future of the individual. You can refer to the table below with a grain of salt.

It should only be used as a guide and certainly has no conclusive evidence.

IQ level=probable job or occupation=% of population

Above 120=professors, lawyers, dentists, physicians=10%
110-120 (good enough IQ range) =teachers/instructors=20%
90-110=typists, clerks, front line receptionists=50%
80-90=fast food attendants=10%
below 80=lawn mowers, trash pickup service=10%

Having a high IQ may be good for highly complex jobs. Nonetheless, any normal individuals will need a normal range of Intelligence Quotient around the 100 bracket.

IQ test means Intelligence Quotient,with the help of IQ tests intelligence test you can measure your ability of your work in any field, if you get high IQ level in IQ intelligence test that means there is chances of highly complex jobs.
