It depends on who you ask. Some Researchers would say yes. They argue that correlations between ratings provided by multiple raters provide the “correct” estimates of the reliability of job performance ratings (Schmidt & Hunter, 1996; Viswesvaran et al., 1996). However, Murphy and De Shon (2000) provide an interesting insight into why this may not […]

What is Domain Sampling?

With Domain Sampling, tests are constructed by randomly selecting a specified number of measures from a homogeneous, infinitely large pool. A sample of items is reliable to the extent that the score it produces correlates highly with these true scores (Nunnally and Bernstein, 1994, p. 217).
