Selection procedures designed according to the rules established by these cut-of scores are likely
to difer from selection procedures that leave these choices to loosely dened criteria like
`professional judgment,' regardless of the fact that both procedures may be based on the same JA
data. Another example of inference-making aid is the use of a two-way matrix to facilitate the
generation of hypotheses concerning linkages between job activities and KSAs or between KSAs
and selection procedures (Arvey, Salas and Gialluca, 1992; Drauden and Peterson, 1974; Guion,
1980; Sanchez and Fraser, 1994).
