Abstract
In 3 experiments with 72 undergraduates, Ss were asked to evaluate student performance based on 2 sources of information differing in variability. In Exp I the relative variability of test scores and paper grades assigned to a given student had no effect on the weighting of information, and evaluations were based on averaging the 2 types of information. In Exps II-III the weighting of test scores was compared for a highly variable grader and a less variable grader. Differential weighting occurred only when instructions linked variability to reliability. It is concluded that evaluators can assign less weight to a source of information perceived to be less reliable but they will not ordinarily use relative variability of scores as an index of reliability.
