It is human relationships that affect personal well-being, the subjective self-satisfaction of overall life. A\ngood human relationship is based on understanding self and others. Psychological tests associated with a person s temperament or character provide information about human relationships. In this study, we examine the correlation between Enneagram and Pythagoras’ numerology, which express human characteristics numerically. Enneagram and Pythagoras’ numerology, which began in Before Christ, classify people in nine different forms. But it is similar to Enneagram and Pythagoras’ numerology that separates nine divided states into three categories. The study examines the correlation between Enneagram divided into head-type, heart-type, body-type and Pythagoras’ numerology divided into realistic-type, emotional-type, thinking type. To do so, we surveyed 65 students at H university in G-si and investigated the effect of stress and anger index on happiness index depending on classifications of Enneagram and Pythagoras’ numerology.
