Abstract
Subjects were required to make numerical judgments based on a brief inspection of a pair of samples of IQ scores. In Experiment I, each sample within a pair contained 20 scores and the values of the two sample means were varied factorially. The subject was to infer the mean IQ of the school from which the samples were taken. In Experiment II, sample size was varied within a pair of samples. In one group, the subject was to infer the mean IQ of the entire school. In another group, the subject judged the mean IQ if the two samples were combined into a single sample. The data of Experiment I were in agreement with a model that assumes that the judgment of population mean is a simple average of the subjective values of the sample means. The data of Experiment II could be described by a weighted average model where sample means are differentially weighted as a direct function of sample size.
