### 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.
