of experience). Researchers found that inter-rater reliability between the primary psychiatrist and the two other psychiatrists was .62. Because the reliability coefficient is relatively high, we can assume that the BDI is a reliable test to assess the current depth of depression. Similarly, Lahlou-Laforet et al. (2015), which aimed to validate the French version of the BDI in chronic heart failure (CHF) patients, assessed inter-rater reliability of the BDI through 23 interviews rated by three…

When discussing quality in the research it is often measured in terms of validity and reliability, these two are not independent and reliability is usually contrasted with validity. Reliability has to do with producing the same stable and consistent result each time the research is repeated. Reliability is also defined as when results are consistent over the time and an accurate illustration of subjects on the research and if the results can be produced over again under the similar methodology.…

sample” (the general population), “treatment sample” (adolescents under treatment for alcohol use), and the “validation sample” (adolescents with psychological/behavioral problems). This wide range helps add to the data available when determining reliability and validity (Donlon,…

Probability: Coin Tossing Project Student’s name: Institutional Affiliation: Introduction Probability is very essential in determining the likeliness with which an event may or may not take place. It plays an important role in various fields but has been implemented widely in gambling. The con tossing project is aimed at determining the highest level of success with which a particular event carried out multiple times would bare. The guesses were aimed at setting…

about the patient. Many tools are used to assist psychologist in diagnosing patients. These include clinical interviews, assessments, and even neurological tests. These tests may give us sufficient information about a patient as long as it has reliability, and validity. The personality assessments vary in different fields from introvert vs. extrovert to rough vs. mindfulness. The first test assessed whether I was an introvert or extrovert. The second test was a self-reflection test. The…

Reliability Table 4.5 Reliability Test Variable Cronbach’s Alpha N of Items Remark Brand Awareness 0.825 5 Reliable Brand Association 0.757 3 Reliable Perceived Quality 0.763 4 Reliable Brand Loyalty 0.890 5 Reliable After validity test, this is the result of the reliability test. The requirement to be reliable is the Cronbach’s Alpha must be more than 0.7. As seen from the table 4.5 the Cronbach’s Alpha of every variables are more than 0.7 which are remarked as reliable. To be explained, the…

Rotheram-Fuller, the AIR is selected because of high item consistencies reliabilities during split-half tests (0.91 to 0.98) and test-retest reliability (0.74). The Tennessee Self-Concept Scale: Second Edition (TSCS:2; Fitts & Warren, 1996) is used to allow the participants the opportunity to complete a self-report measure covering perceptions, attitudes, and beliefs of the participant. Internal-consistency reliabilities for the TSCS:2 were calculated using Cronbach’s alpha which ranged from…

education was not enough to produce the expected result to the hypothesis. The statistical effect size is less significant when pre-intervention and post-intervention MASS/ProQOL measurements are compared; p-values of 0.70 are considered to have a low reliability (Grove, Gray and Burns 2016)…

significant figures rounds to 4.58. Consistent adherence to these rules is crucial in this course because of the amount of information contained in significant figures-- the number of significant figures can reveal the accuracy of a calculation, the reliability of data, and the specificity with which it was measured. It follows, then, that under-reporting in significant figures wastes information and over-reporting is, in fact, "lying" about the specificity of measurement and calculation. Both…

Which Ones are Reliable Sources of Information? There are several ways in which one can judge the reliability of an online source from the criteria listed in the PowerPoint: The library, online video, audio, and visuals. The library is a very good way to judge the reliability of the sources found online. Peer reviews and scholarly articles can be found within the archives of the library. According to Angelo State University (2015), peer review are articles written by experts and are reviewed…
