IQ, or Intelligence Quotient, is a numerical measure of a person's cognitive abilities relative to their age group. By evaluating a range of cognitive skills, so-called "IQ tests" attempt to quantify the g factor, providing a score that reflects an individual's overall intellectual ability.  An average IQ score is set at 100, with the majority of people scoring within a range around this center point. IQ tests aim to quantify cognitive capability and potential, providing a standardized way to evaluate intellectual abilities across different individuals.

The 'g factor,' or general intelligence factor, is a theoretical construct proposed by psychologist Charles Spearman. It suggests that a single, underlying intelligence influences an individual's performance across various cognitive tasks. In simpler terms, if you're good at one intellectual task, you're likely to be good at others because of this general intelligence. For undergraduates, this concept implies that some people have a higher overall cognitive ability that contributes to their performance in different academic and intellectual areas. It's a controversial yet influential idea in psychology, as it argues for a single, quantifiable measure of intelligence rather than multiple, distinct abilities.

This is an IQ test loosely modeled after Raven's Progressive Matrices. The questions take the form of a 3x3 matrix from which one tile is missing. For each question there are eight possible answers A-H. You must choose the tile that completes that matrix best.
