IQ is short for “intelligence quotient”. It measures a person's intellect or reasoning ability. Depicted in the form of a number, IQ is a score derived from the standard tests designed to measure human intelligence and intellectual potential.
The IQ tests evaluate how individuals use their logic and information for problem-solving, finding answers to questions, and making predictions. These tests have been in use for a long time and are still one of the most common forms of psychological tests in today’s times. Continue reading to learn more about what IQ tests are and how the test results can be interpreted. IQ tests for measuring IQ Standard IQ tests are an amalgamation of clinical assessment, which is designed based on psychological evidence. The assessment program entails various factors used to evaluate aspects, including intelligence, verbal and visual memory, reasoning skills, and processing speed. In the early days, the basic method to measure IQ was to divide mental age by chronological age and then multiply it by 100. Another method involved comparing the individual's score against the scores of others in that particular age group. This method applies standardization to interpret and compare IQ scores. Standard IQ tests are conducted by trained professionals in a properly structured environment. Various assessment measures are used to measure IQ, including the more popular Stanford-Binet, Wechsler series and the Woodcock-Johnson method. Such IQ tests are based on the individuals' traits and characteristics and are designed to account for variability according to norms, including factors like age, socio-economic status and ethnicity of individuals. Therefore, if an individual takes an IQ test, their scores will reflect how well they performed compared to others from the same age group who took the same test. What do the IQ scores mean? Now let’s understand what the IQ scores mean! For most IQ tests, the mean or average score is 100. While different scoring standards may be in use, 100 is the mean. Usually, the average scores lie between 80 and 115 for most tests (deviation of +/- 15 from the mean average). For instance, for the Wechsler and Stanford-Binet tests, scores between 90 and 109 are considered average scores. If you have an IQ of 100, it implies that you have an average IQ score and hence normal problem solving or reasoning skills. In any case, contemporary psychological beliefs dictate that IQ scores should not be taken as an ultimate measure. They do not take into account all personality aspects. For instance, they do not reflect practical or life skills aptitude. For instance, a person with a low IQ score may be an exceptional artist or singer or practicing any other skill and maybe doing very well in life. Therefore, even if IQ is measured to predict a person's success in life, it does not consider all aspects and may not be considered a definitive answer. For accurate iq test, click here.
