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).
[18] [19] A dissertation by Peter B. Gregg provided factor analysis of several studies focusing on parasocial responses and concluded that the specific variables and measures that should be used in future research depend on the aims of particular research projects, and that there is no reason to think that the range of measurable parasocial ...
The critical communicative perspective arises from different theoretical contributions. Jürgen Habermas (1984,1981), in his theory of communicative action, argues that the relationship between subjects should be based on validity claims rather than on power ones, seeing the relevance of the subject's interpretations following Alfred Schütz phenomenology (Schütz & Luckmann, 1974) However ...
In the first couple of seconds, the measurements may be accurate to the nearest centimeter. After five minutes, the accuracy of the measurements may be good only to 100 m, because of the increased distance, atmospheric distortion, and a variety of other factors. So the measurements of distance may exhibit heteroscedasticity.
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 ...
There were four questions that Philipsen sought to answer through his research on the Speech Code Theory: the existence of distinctive speech codes; the substance of the speech codes (whether they contained a vocabulary or way of speaking that held meanings for social constructs and worlds). how speech codes could be observed and formulated.
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 ...
A modern-day example of the dominant-hegemonic code is described by communication scholar Garrett Castleberry in his article "Understanding Stuart Hall's 'Encoding/Decoding' Through AMC's Breaking Bad". Castleberry argues that there is a dominant-hegemonic "position held by the entertainment industry that illegal drug side-effects cause less ...
