Assignment 3 Reliability of Results for the Clerical Test and Work Samples Before interpreting the reliability results for the clerical test and work sample it is a good idea to first define what reliability of measurement is. A measurement is reliable to the extent that it provides a consistent set of scores to represent an attribute. In the majority of the case perfect reliability is never achieved because of the errors that the distinct types of measurement have. If we test the same time more

Validity A really important aspect that has emerged in our project is validity which must be put into consideration when developing and evaluating a language test‚ since it will allow us to evaluate the utility and appropriateness of the test for our particular purpose and context. Therefore‚ the validity of a test can only be established through a process of validation and in order to carry it out‚ a validation study has to be undertaken‚ on the basis of arriving at a conclusion as to whether

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

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

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

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
