Reliability

Most important type of validity is the Construct Validity. Any research is impossible without employing constructs (Shadish et.al, 2002). In every research, we aim to understand or imagine constructs and measure their indicators to make inferences as well as judgements. Locke (2012) explains that construct validity is nothing but validating such constructs depending on their correlations with other variables that are indicators or theoretically related to the constructs in question. In order to…

Although there is an exuberant amount of research disproving that standardized tests are trustworthy and reliable, there are still people who stand behind it for multiple reasons. One reason as to why there are people and colleges who heavily trust the results of these scores is because so many kids take it, and according to statistical measures, the more people who participate in something, whether it be a survey or a test, the more accurate the yielded results are.

Finger blood pressure monitors provide a welcome and handy (no pun intended) alternative to these more popular models. A lot of people are suspicious of finger blood pressure monitors and believe them to be unreliable and ineffective when it comes to delivering a reliable reading of one’s blood levels. While it is…

Results McGill pain questionnaire Melzack (1975) developed the Mcgill Pain Questionnaire (MPQ) in 1975 to assist in evaluating the subjective pain experiences of clients noting that different pain has unique qualities. It made up of 78 pain descriptions divided into three categories, sensory, affective and evaluate (Boyle, Boerresen & Jang, 2015; Melzack, 1975; Melzack, 2005). Malzack (1975) described the three main measures as the pain rating index, which is based on the value assigned to…

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…

EWT is vital in the criminal justice system as a way of testifying in criminal trials and relies solely on the accuracy of the person’s memory.
