Statistical testing for a non-zero heterogeneity variance is often done based on Cochran's Q [13] or related test procedures. This common procedure however is questionable for several reasons, namely, the low power of such tests [14] especially in the very common case of only few estimates being combined in the analysis, [15] [7] as well as the specification of homogeneity as the null ...
They relate to the validity of the often convenient assumption that the statistical properties of any one part of an overall dataset are the same as any other part. In meta-analysis, which combines the data from several studies, homogeneity measures the differences or similarities between the several studies (see also Study heterogeneity).
Homogeneity and heterogeneity; only ' b ' is homogeneous Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.A homogeneous feature is uniform in composition or character (i.e., color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous ...

Cross-cultural studies, sometimes called holocultural studies or comparative studies, is a specialization in anthropology and sister sciences such as sociology, psychology, economics, political science that uses field data from many societies through comparative research to examine the scope of human behavior and test hypotheses about human behavior and culture.
Cultural psychology is often confused with cross-cultural psychology.Even though both fields influence each other, cultural psychology is distinct from cross-cultural psychology in that cross-cultural psychologists generally use culture as a means of testing the universality of psychological processes rather than determining how local cultural practices shape psychological processes.

An early proponent of the term was the Guyanese writer Wilson Harris, who wrote in The Womb of Space (1983), that "cultural heterogeneity or cross-cultural capacity" gives an "evolutionary thrust" to the imagination. [3] [4] Anthropology exerted a strong influence on the development of cross-culturalism in literary and cultural studies.
Cross-cultural psychology is differentiated from (but influences and is influenced by), cultural psychology, which refers to the branch of psychology that holds that human behavior is strongly influenced by cultural differences, meaning that psychological phenomena can only be compared with each other across cultures to a limited extent.
