Reliability and Validity

I. Reliability of a Test

The reliability of a test is defined as its degree of consistency, stability, accuracy and predictability hence the repeatability of its scores. Generally, it refers to the extent to which the ultimate results of a given test are consistent over time thereby presenting a degree of accuracy representative of the total population considered under the study. Reliability is quantified in terms of reliability coefficient. The reliability coefficient give insight on the significance of the scores (Waltz, Strickland, & Lenz, 2010). A high reliability coeffiecient implies that the findings are considerably plausible, while a low reliability coefficient implies that the ...

I believe that it is not true that decision making follows a logical, linear progression in our mind as we think over a decision. This is because the rational decision making model makes a lot of assumptions that make it fundamentally flawed. The various steps that are followed in the model give rise to assumptions that form the basic weaknesses of the model and therefore lead the questioning of the truthfulness of the model.
The model assumes the availability of all the relevant information for the decision making process. Perfect information for decision making cannot exist and there will always be ...
