Human reliability

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…

2. There is a good, positive correlation between the six variables in the HC scale. The Cronbach Alpha is .769. From looking at the Inter-Item Correlation if I delete any variable the Cronbach Alpha will go down so there is no need to delete anything. The SE scale Cronbach Alpha was .686, after looking at the Inter-item Correlation chart all of the variables were positive but there were a few variable that were low. If I was to delete any variable the Cronbach Alpha would decrease. So the…

Validity of screening tests in the medical field and the field of psychology is extremely important. These tests help decipher if an individual needs to proceed with further assessments (Gregory, 2011). Without validity of tests, one would not be able to accurately screen for mental health disorders or ailments within the body (Gregory, 2011). Medical screening tests coined the words “sensitivity” and “specificity” while testing for diseases (North Carolina School of Science and Mathematics…

to improve the validity and reliability of data gained from such research methodologies. Some methods of research may give better and more reliable data than other methods. Each method comes with its advantages and disadvantages and some are more suitable for use in certain situations than others. Validity is about how accurate the results of a research are and whether the research piece has the ability to test and research the things it set out to achieve. Reliability is about how trustworthy…

understand what is reliability and validity first. According to David S. (2010), objectivity and credibility are the technical terms that reliability and validity of the research refer to. Polgar, S. and Thomas, S.A. stated that accuracy of the test procedure is what validity concerned with. They also pointed out that reliability is the characteristic of reproducibility and consistency of the results of a measurement step. There are different types of test validity and reliability, for example,…

Reliability, or precision, can be defined as the degree to which a measurement is able to be reproduced with nearly the same value when evaluated several times with no change to the underlying trait being measured. Inter-rater reliability is “ the consistency with which two or more judges rate the work or performance of test takers.(Kelley & Littenberg, 2015). Reliability is often a misconstrued measurement idea. However, the reliability of a test scores bears on decisions regarding the…

Testability The criterion of testability, the forth step in theory evaluation, focuses on measuring the theory content. The testability criterion is accomplished when the grand and middle-range theories are empirically tested. Testability establishes the scientific usefulness of the theory. The testability of a grand theory necessitates it branching into one or more middle-range theories. The testability of a middle-range theory involves reviewing the research methodology related to the theory,…

“Validity and reliability are integral foundations underpinning assessments of physiological parameters.” I have been asked to critically analyse this statement and to support my findings with appropriate examples. To do this I must consider what exactly is reliability and validity and how they affect the physiological parameters of assessments. “Reliability is a measure of the magnitude of repeatability or consistency a test exhibits.”(Ratamess, 2012). What this means is if an athlete…

Organizations posses a lot of information, including strategic plans, trade secrets, cost information, legal documents, and process improvements. Of course, preserving the confidentiality the organization’s intellectual property is the basic objective of information security. Protecting the privacy of their customers’ information is also equally important. That means a company and its management team is also responsible in protecting confidentiality and in implementing privacy controls. If they…

During the meeting, Ken gets upset by Mrs Boyle’s professionalism as she does not display the ‘normal’ human emotions towards him. It is through the lack of emotions, that causes Ken to feel like a patient, instead of a human which emphasises how medical institutions can have negative effects on individuals. The negative tone of “the very exercise of your so-called professionalism makes me want to die” (Page 34)…
