Question

Explain predictive,incremental (ΔR2) and concurrent validity


Answer

How well does information i got on an interviewee predict them doing well on the job ?

Goal: Reduce uncertainty in hiring decisions

Prerequisite: Understanding what explains variance in the outcomes

Multple correlations can be used to reduce uncertainty (concept of assessment centers: collect many sources of information)

Combine predictor variables to increate the incremental validity ΔR2

example

Concurrent validity can be built with the same process from internal data of already employeed workers. (often done using assessment centers)

RISK!: Bias leading to hiring the same (potentially bad) workers, that are just the same kind that we already have. (doesnt help with diversification)
