II. Design The most efficient and easiest way to carry out this experiment would be using repeated measures‚ using the same sample of participants in both sets of conditions‚ deceiving participants to avoid any internal validity issue. Allowing a long time gap between conditions or changing the mentioned conditions would avoid participants from finding out the aim of the experiment‚ or biasing it. Single blind is the best method that can be used in this experiment

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

This analysis provides assessment of the theory measured by using the empirical evidence of the validity of the items based on overall fitness of the model and the construct validity (Hair et al.‚ 2010). A measurement theory refers to a set of theoretical‚ systematic‚ and logical assumptions that suggests path between underlying constructs and items. The construct validity is the fundamental requirement for testing the theory further (Carmines and Zeller‚ 1979; Steenkamp and Trijp‚

effectiveness Using selection methods with good predictive validity is important but this does not guarantee that the procedure will be cost effective. If validity were perfect‚ error—free selection could be achieved. The performance of candidates on scores would be reproduced in their work performance.
