Construct, Internal, and External Validity Essay - 762 Words

Construct validity has to do with establishing correct operational measures for the concepts being studied (Yin 2009, p. 40). Yin (2009), writes that researchers can improve construct validity construct validity can be if multiple sources of data is employed (triangulation of data), establishing chain of evidence, and reviewing the report with their informants (p. 41). In making sure that one can draw a meaning and useful inferences from scores on particular instruments of data collection and to demonstrate the accuracy of their findings, Creswell (2013) also advice the use of member checking and triangulating data (p. 201). Quarm (2009) and Sarquah (2008) both used several data sources (interviews, documents, media, and internet) in†¦show more content†¦Both studies are said to be exploratory in nature. For example, Quarm (2009) study seek to describe the main actors and the strategies they employed to push the domestic violence bill onto the government agenda for attentio n whereas Sarquah (2008) study seek to describe the main factors affecting the implementation of the fiscal decentralization policy in Akuapem South district of Ghana. 8.3 External Validity Yin (2009) defines external validity as establishing the domain to which a study’s findings can be generalized beyond the immediate case study (p.40). It has to do with replication of results; generalization occurs when the same procedures are used by another researcher, the same results will be produced. Two types of generalizations have been identified by Yin (2009); these are â€Å"statistical generalization† which rely on sample survey data) and â€Å"analytical generalization†, which comes from case studies like experiments (p.43). In analytical generalization researchers try to generalize a set of findings to some broader theory (ibid). Both Quarm (2009) and Sarquah (2008) aimed at making analytical generalization hence both used theories in their single-case studies. Quarm (2009) study is analytically generalizable to models of agenda setting of domestic violence law in Ghana with respect to NGOs but not the agenda setting of other policies in Ghana. Sarqu ah (2008) findings in similar way can on be generalized to theories ofShow MoreRelatedExternal, Internal, and Construct Validity Essay1316 Words   |  6 PagesValidity pertains to both the methods and the design of a research study and indicates â€Å"the degree with which correct inferences can be made from the results of a research study† (Indiana University Of Pennsylvania, 2010). According to Trochim and Donnelly, there are four types of validity including conclusion, internal, construct, and external (2008). In this assignment, three of these types will be discussed. Internal validity is the extent to which a test measures what it claims to measure. ExternalRead More Validity: External, Internal, and Construct Essay examples2009 Words   |  9 PagesValidity In research paradigm, validity and reliability are the most basic characteristic issues used in qualitative and quantitative analysis. Validity as a psychometric standard is embedded in a positivist approach, which is relevant in reflecting on the qualitative point of view ascribed to the establishment of the truth. In view of this, definition of positivism ascribe to a theory systematic to validity. Additionally, other empirical conceptions culminating from resided validity includeRead MoreCompare and Contrast the Characteristics of External, Internal, and Construct Validity1790 Words   |  8 PagesCompare and Contrast the Characteristics of External, Internal, and Construct Validity Validity is an important aspect of the research design. For instance, in research the uses statistics as the primary form of measurement. Validity applies to the truth of a standard. A measure is valid, in general, when it (Renata, 2011, 1) includes what it devised to measure. Renata (2011) explained, Internal and external validity are the two primary types of validity (para. 1). However, both display diverse aspectsRead MoreThe Principles Of Reliability And Validity Essay928 Words   |  4 Pagesscientific proof, then validity and reliability are what you need. In the work by Xie, Huang (2014) they describe the following: The principles of reliability and validity are fundamental cornerstones of the scientific method. Reliability is defined as the extent to which a measure is repeated under ideal conditions. Validity refers to the degree to which a test measures what it purports to measure. Establishing good quality studies need both high reliability and high validity. (p.326). BothRead MoreCommon Tests of Reliability882 Words   |  4 PagesThese inaccuracies could mistakenly be attributed to the research variables. One of the most common tests of reliability is replication, which takes the form of test-retest, parallel forms of instruments, odd-even item correlations, or measures of internal consistency (Campbell Stanley, 1963). In inter-rater reliability, different people are utilized with the same test. This is also a strategy used to validate the reliability of data coding in qualitative research. For test-retest procedures, measurementRead MoreExternal Validity And Its Impact On The World1344 Words   |  6 Pagesstatistics class I have had the amazing opportunity of learning about various validities and data’s. The three validities in which I learned about were, internal, external and construct. I will explain these validities as well as experimental data and their usefulness in the world. Lastly, I will explain how one of these data could be useful to me in resolving an issue that I may meet in life. External Validity includes generalization claims, or the study s capacity to sum up the outcomesRead MoreA Study That Affects College Students Of Sleep1357 Words   |  6 Pages 1. Give a one-sentence definition of internal validity. As an example, I’m going to conduct a study that deprives college students of sleep, to prove their grades will go down as a result. If I found a link between reduced sleep and reduced grades, what is an internally valid conclusion about the results of this study (be specific)? Internal validity is isolating certain variables to determine how well an experiment goes. In your example, we are determining the link between sleep and a decreaseRead MoreNegative Consequences Of Sharp Drop Of Crude Oil Prices On The Nigerian Economy1485 Words   |  6 Pagesfocus more on how to measure and ensure the validity of the study, including the data collection, data analysis and overall methodology, design and even research findings. However, we are going to focus more on the validity. VALIDITY: Validity in general is the determination of how sound the information presented in the study is; based on the facts that a valid research study will present valid and believable findings (Trochim, Donnelly, 2008). Validity of a research study relies on the validlyRead MoreA Contemporary Analysis Of Accounting Professionals Work Life Balance1741 Words   |  7 PagesA research paper is only considered valuable if it is both valid and reliable in measuring the constructs that it claims to. This paper is aimed at evaluating the validity and reliability of the research paper titled â€Å"A Contemporary Analysis of Accounting Professionals’ Work-Life Balance† by Buchheit, Dalton, Harp and Hollingsworth, published in the Accounting Horizons Journal in March 2016 in its first issue of volume 30. The research paper endeavoured to provide answers for two main research questionsRead MoreExternal, Internal, And Construct Essay738 Words   |  3 PagesValidity: External, Intern al, and Construct Internal validity measures what it intends to measure or, more generally, if it examines what it sets out to examine. In effect, a valid study gives real answers to the research questions and provides a real test of the hypotheses. According to Aken, Berends, and Bij (2007), â€Å"Internal validity concerns conclusions about the relationship between phenomena. The results of a study are internally valid when conclusions about relationships are justified and
