Weâve all heard of the term IQ (or Intelligence Quotient). But what does it really represent and how significant is your or your childâs score is an IQ test? What does it really mean to have a low, moderate, or high IQ? A standard IQ test is designed to measure a personâs performance relative to their peers, most commonly, their age group. This is particularly the case with children and adolescents.
An IQ test score is calculated based on a norm group with an average score of 100 and a standard deviation of 15. The standard deviation is a measure of spread, in this case of IQ scores.A standard devation of 15 means 68% of the norm group has scored between 85 (100 â 15) and 115 (100 + 15).bout 2% of the population has an IQ score lower than 69. Such a low IQ score often is hard to measure using a regular intelligence test. Very high IQ scores are also hard to determine accurately. This is because you need a lot of reference measurements to determine a specific score reliably.
