Reliability of Test Reliability is defined by Joppe (2002,p.1) as the level of consistency of the obtained results over a period of time as well as an accurate representation of the population under study. If the outcome of the study can be reproduced using a similar methodology then the instrument used in the research are said to be reliable. It is worth noticing that there is an element of replicability as well

As shown in Appendix 2 these report gives a complete and detailed picture of candidate's personality type, classifying him to one of five main types: A-director, B - socializer, motivator, people person, C - thinker, analytic, D - supporter, X which means that personality has two types synergized. Interviewing as the most used employee screening skill Another very effective method of prospective employee evaluation is evaluation interview. Evaluation interview was a theme

b) Preexperimental design and quasi-experimental design- a Preexperimental design is a design that acts as a blueprint for the actual research and a quasi-experimental design is a design that resembles a quantitative or qualitative research design but lacks controls. c) history and maturation -- history refers to events that take place outside of the experiment that may affect participants' responses to the experiment and maturation refers to the change that occurs

Presumably, the reliability of the responses between a monitored study and an unmonitored study could be validated by consistent reportage from the peer and the incumbent. This method was also used to control for the study's overall validity: the study would be a more valid measure of counterproductive work actions and their relationship to work stressors if an outside source validated the incumbent's responses. The study's authors still acknowledge a

Research instruments fall into two broad categories: those compiled by the researcher him or herself in the form of recorded observations, logs, and rating scales and those completed by the interview subject him or herself in the form of questionnaires and interviews. Regardless of the instruments used, research studies should be guided by acceptable standards of validity and reliability. "Validity is the extent to which an instrument measures what it
