Standard deviation commonly used in dustrial and agricultural production for example, biochemistry, physics and other experimental data for statistical analysis, in theory, there is no inverse operation. However, some special circumstances, given the need to turn to get some close to the standard deviation of the source data. This simple but useful program allows users to enter the mean and standard deviation, and other auxiliary parameters, depending on the input stochastic simulation of multiple source data close to meet the conditions, on the one hand to facilitate users for data and statistical analysis of the results of multi-angle verification, but it is also easy to learn to understand the standard deviation formula, for the relevant mathematics, science teaching numerical methods provide some help. EL future will gradually develop other statistical analysis programs, exchanges with colleagues.
