What does IQ stand for in the context of intelligence measurement?

In the context of intelligence measurement, IQ stands for Intelligence Quotient. This term was originally developed in the early 20th century to provide a standardized way of measuring human intelligence through various cognitive tasks and exams. The concept is rooted in the idea that intelligence can be quantified and compared across individuals, helping to identify areas of strength and potential areas for improvement. The score derived from these assessments aims to represent a person's cognitive abilities relative to others in their age group.

The other options do not accurately represent the widely accepted definition of IQ. Intended Quotient suggests a goal-oriented measure rather than a standardized assessment of intelligence. Interpersonal Quotient implies a focus on social skills and emotional intelligence, which IQ does not encompass. Indicator of Qualities is vague and does not specifically relate to cognitive measurement. Therefore, the correct answer clearly aligns with the established understanding of IQ as a measure of intelligence through standardized testing.
