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 ...

1. Explain the 4 main classifications of anesthesia, and provide an example of each.
Anesthesia is a reversible, pharmacologically induced state of analgesia, loss of skeletal muscle reflexes and/or responsiveness, amnesia, decreased stress response. Depending on the type of anesthesia used, the aforementioned effects may occur as one or they may occur together simultaneously. Generally, there are four major classifications of anesthesia; local, regional, general anesthesia and moderate sedation (Brookside Associates, 2010).
General anesthesia (GA) depresses the central nervous system producing a reversible loss of consciousness and skeletal muscle reflexes and analgesia. Basically, general anesthesia has three phases; induction, ...
