Heterogeneity

Heterogeneity refers to the presence of diversity or differences within a group or system. It means that the members or components are not identical and can vary in characteristics, behaviors, or features. For example, in a population, people may differ in age, preferences, or health. Recognizing heterogeneity is important because it influences how we analyze, interpret data, and make decisions, ensuring that different factors or types are appropriately considered rather than assuming everyone is the same.
