Definition
Noun: 1. The quality or state of being diverse in character or content; the condition of being composed of parts or elements that are different from one another. It refers to a lack of uniformity or similarity within a group, system, or mixture.
Usage
Heterogeneity is a formal term used to describe a collection or system where the constituent parts are varied or dissimilar. It is often used in academic, scientific, and technical contexts (e.g., statistics, biology, sociology, data analysis) to discuss diversity within a sample, population, or material. It is the opposite of homogeneity.
Examples
