Question

Quizplus · Accepted Answer

The encephalization quotient (EQ) is a measure of an animal's brain size relative to the expected brain size for an animal of the same body size. It compares an actual brain weight to the predicted brain weight for an animal of that size, providing insight into the relative braininess of different species.
