Quizplus · Accepted Answer

The formula for calculating IQ is based on the ratio of mental age to chronological age. This is represented as (mental age / chronological age) x 100, which gives the IQ score. Choice A is incorrect as it uses years in education instead of chronological age. Choice C is not a valid formula as there is no correlation between mental age and shoe size. Choice D multiplies the ratio by 200 which is not necessary as multiplying by 100 gives the IQ score directly. Choice E is also incorrect as it uses years in education instead of chronological age.
