le: the reproductive success; was measured in like fashion. Since the reproductive success can not be ranked, only taken or assessed in terms of ‘ranges’ (correlations), it is clearly also a ratio measurement. Both positive and negative correlations were unearthed, discussed, and set in table form. Given the amount of information available for Cronk’s analysis, excess is known about each variable, giving precise measurements; these precise measurements are defining characteristic of ratio measurements (Donald 2001:lecture of February 6.)Assessing the Validity and Reliability of the StudyThe reliability and validity of Cronk’s proposition are efficiently and clearly proven in his article. As previously mentioned, considering all the variables and correlations that have been compared and contrasted the author can make evident that certain factors have more or less relevance in lieu of the case. Due to the sheer amount of information gathered by other researchers and the application of Cronk’s accumulated data, contrasted by one another, reliability becomes unmistakable. The proposition adheres to stability, equivalence, and homogeneity. In utilizing other hypothesis, Cronk is able to prove regularities among all of his samples, as well as those done by other anthropologists, having done studies in similar fields with similar populations. Because Cronk is able to clearly correlate all possible and relevant variables with respect to reproductive success and livestock wealth, and due to the duration of the study, he can be assured of reliability. Assessing factors of age, education, wage employment, access to health care, productivity of wives and children, bridewealths (through daughters), wives' reproductive success, age at first marriage, and finally, polygyny, Cronk has ample evidence to show reliability and consistency. As we shall see, Cronk’s proposition holds validity and therefore, clearly, also m...
