In the context of the historical development of intelligence measurement and intelligence quotient (IQ), upon deep analysis of the concept of 'Mental Age' propounded by Alfred Binet and the formulas of intelligence quotient developed by William Stern and Lewis Terman, which of the following statements is most appropriate and scientifically true?

In the history of intelligence measurement, William Stern propounded the IQ formula in 1912 as the ratio of mental age to chronological age. Subsequently, Lewis Terman of Stanford University multiplied this ratio by 100 during the revision of the Stanford-Binet Intelligence Scale in 1916 to remove decimals and give it a modern percentage form. To know more about this historical development, you can refer to the Wikipedia reference.
