An objective is something that a person or group plans to achieve. It can also refer to a viewpoint or approach that is unbiased, impartial, and based on facts and verifiable evidence. In contrast, subjective information or a subjective perspective is based on opinion, emotion, or feelings. The difference between objective and subjective information is that objective information is based on facts, while subjective information is based on feelings or opinions. The word "objective" can also be used as an adjective to describe something that is undistorted by emotion or personal bias and is based on observable phenomena. For example, an objective test is limited to choices of fixed alternatives and reduces subjective factors to a minimum.
