Didactic and Production Software for Computing Sample Variances,
Abstract
The standard deviation (or equivalently the variance) of a sample of numbers is one of the most elementary concepts in statistics. Yet this computation harbours a number of serious difficulties, especially when the sample is large and the standard deviation is small relative to the mean. This contribution will describe prototype software for both didactic and production use to allow reliable calculation of sample variances (or equivalently standard deviations), for a wide variety of sample sizes and data characteristics. Several illustrations of the software and its evaluation will be presented, if appropriate accompanied by a live demonstration.
