The comparative method

The labiovelars may be thought of as velar stops articulated with simultaneous lip-rounding. It is notable that the languages that have a velar for the Proto-Indo-European labiovelar stops e. Earlier scholars attached great significance to this fact and thought that it represented a fundamental division of the Indo-European family into a western and an eastern group.

The comparative method

For example, the scale location might represent the perceived quality of a product, or the perceived weight of an object. The BTL is very closely related to the Rasch model for measurement. Thurstone used the method of pairwise comparisons as an approach to measuring perceived intensity of physical stimuli, attitudes, preferences, choices, and values.

He also studied implications of the theory he developed for opinion polls and political voting Thurstone, Transitivity[ edit ] For a given decision agent, if the information, objective, and alternatives used by the agent remain constant, then it is generally assumed that pairwise comparisons over those alternatives by the decision agent are transitive.

Most agree upon what transitivity is, though there is debate about the transitivity of indifference. The rules of transitivity are as follows for a given decision agent. Probabilistic models require transitivity only within the bounds of errors of estimates of scale locations of entities.

The comparative method

Thus, decisions need not be deterministically transitive in order to apply probabilistic models. However, transitivity will generally hold for a large number of comparisons if models such as the BTL can be effectively applied.

Using a transitivity test [1] one can investigate whether a data set of pairwise comparisons contains a higher degree of transitivity than expected by chance. Argument for intransitivity of indifference[ edit ] Some contend that indifference is not transitive.

Consider the following example. Suppose you like apples and you prefer apples that are larger. Now suppose there exists an apple A, an apple B, and an apple C which have identical intrinsic characteristics except for the following.

Suppose B is larger than A, but it is not discernible without an extremely sensitive scale. Further suppose C is larger than B, but this also is not discernible without an extremely sensitive scale.

However, the difference in sizes between apples A and C is large enough that you can discern that C is larger than A without a sensitive scale. You are confronted with the three apples in pairs without the benefit of a sensitive scale.

Therefore, when presented A and B alone, you are indifferent between apple A and apple B; and you are indifferent between apple B and apple C when presented B and C alone. However, when the pair A and C are shown, you prefer C over A.Vertebrate models (e.g., rodents, swine, nonhuman primates) have long played a central role in biomedical research because they share much in common with humans with respect to genetics, development, physiology, behavior and disease.

The comparative method is defined and analyzed in terms of its similarities and differences vis-à-vis the experimental and statistical methods. The principal difficulty facing the comparative method is that it must generalize on the basis of relatively few empirical cases.

The Comparative Method With this post I am returning to my discussion of methods available for studying the Gospels. I will devote probably three posts to a method that I call the “comparative method.”. Linguistics: Linguistics, the scientific study of language. The word was first used in the middle of the 19th century to emphasize the difference between a newer approach to the study of language that was then developing and the more traditional approach of philology.

The differences were and are largely.

comparative method noun Historical Linguistics. a body of procedures and criteria used by linguists to determine whether and how two or more languages are related and to reconstruct forms of their hypothetical parent language.

Linguistics - The comparative method: The comparative method in historical linguistics is concerned with the reconstruction of an earlier language or earlier state of a language on the basis of a comparison of related words and expressions in different languages or dialects derived from it.

Ragin’s The Comparative Method proposes a synthetic strategy, based on an application of Boolean algebra, that combines the strengths of both qualitative and quantitative sociology. Elegantly accessible and germane to the work of all the social sciences, and now updated with a new introduction, this book will continue to garner interest, debate, and praise.
