Validity Validity addresses whether the assessment measures what it is supposed to measure (Gormley‚ 2011; Van der Vleuten‚ 1996). For both the OSCE stations that I have designed‚ I have created a complimentary mark scheme. As discussed previously‚ I opted to produce a global rating scale for the history-taking station and a checklist for the procedural skill station (appendix 1 and 2). Weighting of items can improve validity of a checklist‚ which can affect which trainees pass or fail (Sandilands

Validity is about the extent to which a piece of research in finding out what the research is finding out what the researcher intents to find out. The idea of validity means that something is true and can be believed. When people say ‘that’s a valid point”‚ they mean that the point is relevant‚ meaningful and believable. It is concerned with truth and value‚ that is whether conclusions are correct or not. It also considers whether the method‚ approaches and techniques actually relate to what is being

Exam-type questions on Thrust Bearing design 1. You have been asked to design a minimum power-loss‚ uni-directional‚ thrust bearing for an horizontally-mounted‚ axial‚ ammonia compressor in a nitric acid plant. The compressor has a shaft diameter of 100 mm and generates a thrust of 15kN when operating at 6‚000 rpm. The thrust is negligible at zero speed. a. What type of thrust bearing would you recommend and why? b. What are the physical reasons why a dry‚ PTFE bearing would

PEER TO PEER ARCHITECTURE : Synopsis In a peer-to-peer (P2P) network‚ every machine plays the role of client and server at the same time. Although a P2P network has a number of advantages over the traditional client-server model in terms of efficiency and fault-tolerance‚ additional security threats can be introduced. Users and IT administrators need to be aware of the risks from propagation of malicious code‚ the legality of downloaded content‚ and vulnerabilities within peer-to-peer software.

Discuss issues of reliability and validity associated with the classification and diagnosis of phobic disorders (8 + 16 marks) A phobia is a persistent fear that is excessive or unreasonable which must meet a set of criteria given in the DSM. A clinical diagnosis is made if there is no other possible physiological cause and if the symptoms cannot be better accounted for by another disorder. The individual also recognises their behaviour is unreasonable and the severity of the fear interferes with

Exploring Reliability and Validity Researchers have constructed instruments in attempt to empirically measure values and culture belief systems of people and societies. In order for one to measure what some may consider subjective meanings; concrete definitions were given to the types of values that were examined in the “Values and Motives Questionnaire” (Values and Motives Questionnaire‚ n.d.‚ p.1). The values examined were categorized as interpersonal‚ extrinsic‚ and intrinsic values (Values and

Discuss issues surrounding the reliability and validity of classification and diagnosis for Schizophrenia. Schizophrenia is a psychological disorder which is sometimes referred to as split minds. Sufferers can be known to show symptoms of delusions‚ hallucinations as well as catatonic behaviour. If we are looking at the validity of something it means we are measuring what we are claiming to measure‚ and if we are looking at the reliability of something it means if we repeat the process over

Reliability and Validity Ebony Johnson University of Phoenix Reliability has to do with the quality of measurement and is the consistency of repeatability of measures. To define it precisely researchers first have to learn about the foundation of reliability- the true score theory of measurement. Then researchers need to understand the different types of measurement error because they play a key role in degrading reliability. Because reliability can only be estimated there are different types
