### Applications of Binary Matrices

Note: if you cannot remember what a binary matrix is, revise notes for 1.1 Matrices: Definition and Unique Cases.

**Binary matrices** are used to represent** correlation** between datasets. If two categories are **correlated**, a **1** is placed in the element corresponding to the two, if they are **not**, a **0** is placed instead.- They are also used to represent
**dominance.** If one category is “greater than” another, a 1 is placed in the corresponding element, else a 0 is placed instead.

Note: we will further explore dominance matrices in notes 1.7 Matrix Applications: Dominance Matrices.
