Heterogeneity is a diverseness of constituent structure.

Heterogeneity or heterogeneous may also refer to:

Data analysis

Heterogeneity in statistics
Heterogeneity in economics
Study heterogeneity, a concept in statistics
Heterogeneous relation

Biology and medicine

Heterogeneous conditions in medicine are those conditions which have several causes/etiologies
A heterogeneous taxon, a taxon that contains a great variety of individuals or sub-taxa; usually this implies that the taxon is an artificial grouping
Genetic heterogeneity, multiple origins causing the same disorder in different individuals.
Allelic heterogeneity, different mutations at the same locus causing the same disorder.

Chemistry

A heterogeneous reaction, a reaction in chemical kinetics that takes place at the interface of two or more phases, i.e. between a solid and a gas, a liquid and a gas, or a solid and a liquid
A heterogeneous catalysis, one in which the catalyst is in a different phase from the substrate

Ecology

Heterogeneity in landscape ecology, the measure of how different parts of a landscape are from one another.

Computer science

Heterogeneous computing, electronic systems that utilize a variety of different types of computational units
Semantic heterogeneity, where there are differences in meaning and interpretation across data sources and datasets
A data resource with multiple types of formats.

+'''[[Heterogeneity]]''' is a diverseness of constituent structure.
+'''Heterogeneity''' or '''heterogeneous''' may also refer to:
-'''Heterogeneous'''  is an adjective used to describe an object or system consisting of multiple items having a large number of structural variations. It is the opposite of ''[[homogeneous]]'', which means that an object or system consists of multiple identical items. The term is often used in a [[science|scientific]] (such as a kind of [[catalyst]]), [[mathematics|mathematical]], [[sociology|sociological]] or [[statistics|statistical]] context.
