The book chapter explores the subject of measurement, with a specific interest in operations procedures for analyzing validity and reliability challenges in research. The author uses the opportunity to outline the triangulation process of analysis in the first section of the paper. Secondly, in qualitative testing paradigms, the researcher explores the term significance and durability and how they are evaluated. Finally, the report is concluded by presenting the best available approaches in a research sample to explain reliability and validity, building on triangulation and illustrating the results of qualitative experiments.
Arguments of the Author
The writers agree that standardization is a significant phenomenon in qualitative analysis. Validity and reliability are substantial aspects of emphasis in the broadcast context. He describes validity as the credibility of the results, while reliability is the consistency of the research. The author focuses on the best possible methods of eliminating errors that can arise in analysis by implementing the above criteria (Hagan, 1997). These variables play a critical role in establishing an accurate representation of the observations achieved during the analysis.
The renowned scholar argues that to achieve validity and reliability, the researcher needs to use the triangulation method. In simple terms, triangulation refers to the application of multiple ways to determine the same phenomena. The use of the varied approaches to the same items should indefinitely yield similar results. Triangulation provides the researcher with the ability to achieve the reliability and validity of the products. In other words, it is the logical device for assessing the authenticity of any research.
The researcher demonstrates that using test-retest, split-half, and multiple techniques typically achieves efficiency and validity. In the test-retest approach, two different ways are used to perform the tool, and the outcomes are compared later. On the other hand, the split-half strategy requires an administration with perfectly contextually-correlated random halves (Hagan, 1997). According to the writer, in order to better obtain the desired effects, the chapter recommends the implementation of the different modes of organization of the experiments.
Finally, the authors of this paper asserts that some of the main factors that lead to errors in most research studies are little professional self-esteem, design faults, and lack of complexity in technique. The above causes, along with the low degree of expertise, the adverse scientific atmosphere and inter-jurisdictional conflicts, are the hallmark of the research errors. In their opinion, the renowned scholars continue to argue that most of the judicial researches have failed to meet the required standards due to the above varied elements.
Arguments against the Author Position
Based on empirical knowledge provided, it is essential to note that the author neglected to clarify how the three methods can be successfully combined to facilitate the findings achievement. Ideally, it is claimed that the availability of various methods has a powerful impact on producing the best outcomes. In the best interest, the renowned analysis should work on the best possible ideas that should be employed to make these strategies become viable. The combination of these proposed mechanisms will not only promote the delivery of the best possible results but also ensure that criminal justice institution improves in their service delivery.
Conclusion
Based on the provided analysis, it is clear that validity and reliability are core factors that must be achieved in every research. In most cases, they provide the research with the required strength that it requires. Therefore, the researchers must strive to use some of the best techniques that will promote the achievement of these results in an experiment. They must dedicate themselves as well as employ all the possible efforts necessary for the realization of the best results.
