## Matrix Diagram (Y-Shaped) Sometimes also called ：( **Y-Matrix**, **Y-Matrix Diagram** )

Y-Matrix is one of six forms of Matrix Diagram. A Matrix Diagram shows the relationship between items. At each intersection a relationship is either absent or present. It then gives information about the relationship, such as its strength, the roles played by various individuals or measurements. It can be shaped differently depending on how many groups must be compared. The other five differently shaped matrices are: L, T, X, C, R and roof-shaped.
