The family sociogram is a graphical representation of a person's relationships with his family. This diagram also depicts the collateral members and the social group outside. Creating a family sociogram is a simple process. The patterns formed by the lines represent the patterns of relationships and subgroupings within the group and the group's overall cohesion. In the diagram, the connection is shown with different colored arrows. The red arrow represents the primary family, yellow represents the secondary family, purple represents friends, and the green represents a mystery man. The group's overall cohesion is moderate in strength.
