(Information Technology Intelligence Quotient) - The measure of one's ability to learn, retain and understand anything related to IT. The calculation is made with inverse weight given to age (as appose to how a normal IQ is calculated) because the assumption is made that someone knows LESS about IT as they grow older.
For example, to calculate a normal IQ, you divide the mental age by the chronological age and multiple by 100 (IQ = (MA/CA) * 100). For example, if a certain child started reading, etc., at the age of 3 (CA) and average children start reading, etc., at the age of 6 (MA), the child would get an IQ score of 200.
However, to calculate an ITIQ, you divide the chronological age by the IT age and multiply by 100. For example, if a certain person learned to use the new iPhone features at the age of 30 (CA) that any 15 year old (ITA) would easily pick-up, that person would get an ITIQ score of 200.
