IQ is considered an interval scale. This means that it measures intelligence in terms of numerical values where the differences between scores are meaningful and consistent. However, it does not have a true zero point, as an IQ score of zero does not indicate the absence of intelligence. Thus, while IQ scores can be compared and analyzed mathematically, they do not represent a ratio scale.
Ordinal.
IQ (Intelligence Quotient) is considered interval-level data. This means that IQ scores have a meaningful order and the differences between scores are consistent and quantifiable, allowing for comparisons between individuals. However, IQ scores do not have a true zero point, meaning that a score of zero does not indicate the absence of intelligence, which is a characteristic of ratio-level data.

The IQ score is a ratio of the average intelligence age to the chronological age. An IQ of 122 means that a 14 year old has the same intelligence as that of an average 17 year old.

The IQ scale is considered interval because the differences between scores are standardized and consistent across the range of scores. This means that a difference of 10 points on the IQ scale represents the same change in intelligence level regardless of where on the scale it occurs.
While IQ itself is a ratio", the data is interval-level data. The IQ was first created in order to relate the mental development of a child to the child's chronological age the IQ. IQ = (MA/CA) * 100 While in theory, a birth one has a MA of 0, so one could make a theoretical argument that IQ data is a ratio level of measurement because it has a natural zero. The fact is, nobody ever deals with 0 IQ because there is no such test for babies. So while theoretically, scores can range any amount below or above 100, but in practice they do not meaningfully go much below 50. Remember a ratio level of measurement is the same as an interval level of measurement with the additional property of a natural zero, where zero indicates none of the quantity is present. We use it for things like distances and prices. If we do not travel at all, that is zero distance and a free item has a 0 price. On the other hand, interval level of measurement allows the data to be arranged in some order and the difference between any two data values is meaningful. Some common examples are body temperature, and years. Years is confusing but time 0 is arbitrary and not really a starting point of time. Also the value of 0 is arbitrary for temps and does not indicate any true absence of heat. s

An IQ test will determine an Intelligence Interval for an individual in a number form. For various number ranges there is a Cognitive Designation. An IQ rating between 85 - 114 is considered Average, 40 - 54 Severely Challenged, and 160 - 175 Extraordinary Genius.
IQ is traditionally the ratio of mental age to physical age multiplied by 100. At the extremes, it's largely meaningless - an IQ of 1 would mean a 100 year old person with a mental age of 1. The average IQ (Intelligence Quotient) is between 90 - 110. So for one to have an IQ of 1 would be highly improbable.
Two examples of interval measurements are temperature measured in degrees Celsius and IQ scores. In both cases, the differences between values are meaningful and consistent, allowing for arithmetic operations, but there is no true zero point that indicates the absence of the quantity being measured. For instance, 0 degrees Celsius does not mean there is no temperature, and an IQ score of 0 does not indicate an absence of intelligence.
