Abstract
Subjects were required to make intuitive estimates of the means of samples of 10 or 20 numbers with auditory presentation. As in previous experiments, performance was fairly accurate, and increased sample size and variance resulted in overestimation. Accuracy was also affected by the value of actual means and there were significant interactions between sample size and variance and between sample size and actual mean. The observed tendency for intuitive estimates to be more accurate with auditory than with visual presentation was thought to be a feature of sequential processing strategies.
