Selection is the process of choosing the trampdidate who best meets the selection criteria. A critical component of validity is reliability. Validity embodies not lone(prenominal) what positive outcomes a selection approach may predict, simply also how consistently (i.e., reliably) The terms: Reliability The method employ should not be influenced by chance, and should be consistent in leave alones if used to assess a person on more than than one occasion. / The extent to which two or more methods let up standardized results or are consistent. Consistency of handbillment is the unfathomed underlying concept of reliability and such it is a truly important standard with which to evaluate any selection methods. 3 types of Reliability 1. Test- Retest Reliability ( it is a strategy described for estimating the reliability in the tray exercised. Its main purpose is to establish the stability of a measure over cartridge holder. The shorter the clip gap, the higher the correlation; the longer the time gap, the lower the correlation. This is because the two observations are related over time -- the closer in time we get the more similar the factors that contribute to error.

Since this correlation is the test-retest estimate of reliability, you can obtain good different estimates depending on the interval. Disadvantage: Applicants may learn from the premiere trial & improve their per ca-caance on the retest, which may result to a reduced in reliability co-efficient. 2. Parallel form Reliability ( When there are two different versions of the homogeneous test or selection procedure, a reliability coefficient can be estimated by correlating the scores obtained on one version with the other. The correlation between the two gibe forms is the estimate of reliability. mavin major problem with this approach is that you have to be fit to generate lots of items that reflect the same construct. ( A more frequently used method, based on the logic of parallel form is that of internal...
