Validity, in essence, has got to do with the extent to which a given research study measures the accuracy of a specific concept – effectively meaning that a study can be said to have passed the validity test if it accurately mirrors that which the researchers set about to investigate. In quantitative research, as Polit and Beck (2012) point out, “researchers strive to design studies that are strong with respect to all four types of study validity” (p. 303). As the authors further point out, while an attempt to enhance one kind of validity may benefit another form of validity, efforts to ensure one kind of validity sometimes end up interfering with the achievement of other validity types. The four kinds of validity to be taken into consideration in the review of a research design are identified as external validity, internal validity, construct validity, and statistical conclusion validity (Balnaves and Caputi, 2001).Internal validity is often been cited as being of utmost importance in research (Polit and Beck, 2012). For a qualitative research to be regarded beneficial and relevant,it has to clearly define or demonstrate cause and effect. In the absence of internal validity, the said case and effect relationship would be weak and therefore,...
Findings would, therefore, be nothing but unwarranted claims.
External validity comes in handy in the measurement of “the extent to which your sample is genuinely representative of the population from which you have drawn it” (Balnaves and Caputi, 2001, p. 89).” Therefore, external validity enhances a study's generalizability aspect. A research that does not have wide applicability does not make the much needed contribution to a specific field of study. While the relevance of internal validity cannot be overstated when it comes to the determination of a program’s effectiveness, for instance, external validity is equally important in seeking to determine how effective the said program is likely to be in other settings.
When it comes to construct validity, it is important to note that for a research study to truly reflect that which the researcher sets about to investigate, its constructs ought to be represented in an appropriate and accurate manner. To achieve this, established methods and standards ought to be utilized in the constriction of tests/research. On this front, a researcher ought to ask whether or not the experiment…
Validity in Quantitative Research Designs Validity Quantitative Research Designs Validity research refers extent researchers confident effect identify research fact causal relationships. If low validity a study, means research design flawed results . Threats to internal validity in quasi-experimental designs Quasi-experimental studies have several issues that lead to lack of internal validity of the study. These occur as a result of the experimental conditions not being highly controlled or randomized. This leads to intervention
Validity in research is a term that refers to the extent with which researchers are confident that they have determined causal relationships through the cause and effect they identify in their study. As a result, validity is an important aspect of research since it helps in determining whether the research design is flawed and the credibility of research findings. There are various kinds of validity that are utilized in determining
Techniques for testing reliability, on the other hand, can be achieved through the test-retest, alternative-forms, and internal consistency methods. Test-retest method administers an instrument to the same population in two different periods/occasions, and the difference between the scores of the first and second administration determines the reliability of the construct under study. Alternative-forms is similar to test-retest method; only, the flow of the instrument in the second administration is
Strengths/Weaknesses of the Quantitative ApproachIntroductionQuantitative research is a widely used approach in public administration research that involves the collection and analysis of numerical data. This approach has several strengths, including the ability to use probability sampling methods to select representative samples, the ability to replicate studies to verify findings, and the ability to collect large amounts of data quickly and efficiently. However, there are also limitations to quantitative research, such
Research Methodologies and Implications for Modern Businesses Today, two of the primary methods of collecting relevant information and interpreting it in unique ways to benefit business operations are qualitative and quantitative methodologies. Although these two research methodologies share some commonalities, they both differ in terms of what types of data is used for analysis and how the resulting analysis is applied in real-world settings. The purpose of this signature assignment is
Quantitative Research Critique Part I Introduction It is important to note, from the onset, that the health and wellbeing of women is often impacted upon negatively by intimate partner violence (IPV). In the past, various research studies have attempted to not only assess the impact of IPV on the health and wellbeing of women, but also the strategies that ought to be implemented in seeking to care for victims of IPV. In
