Definition: To divide something into two distinct and separate parts or categories.

Example: The study aimed to dichotomize the data into two groups for better analysis.

Definition: Describing something that is divided into two distinct parts or categories.

Example: The study presented a dichotomous view of the issue, separating it into two opposing sides.
