Emotional Quotient (EQ) is a way to measure how a person recognizes emotions in himself or herself and others, and manages these emotional states to work better as a group or team.
Intelligence Quotient (IQ) is a value that indicates a person's ability to learn, understand, and apply information and skills in a meaningful way. The major difference between EQ and IQ is what part of a person's mental abilities they measure: understanding emotion or understanding information.
