2. What is IQ?

Coined by German psychologist William Stern in 1912, the intelligence quotient or IQ shows an individual how far above or below an intelligence baseline they fall, relative to others in their demographic. The simple formula using mental age and chronological age, in addition to test performance, became the more accurate tabulation. IQ tests are staples across multiple sectors, but some deride them as nothing more than an indication of how well someone takes a test.
