基于VB.NET的采用多种方法的标准差计算系统

Standard Deviation Computing System with Various Approaches Based on VB.NET

标准差作为反映每个实际变量值与算术平均值的平均离散程度的参数,在仪表、机械、信息类专业领域中占有十分重要的地位。因此,能够采用多种方法专门计算标准差的系统将为相关领域的工作提供很大的方便。本文介绍了基于VB.NET语言环境开发的标准差计算系统,它可以采用多种常用方法,计算一组数据的标准差等参数,并且有直接输入数据和读取文件两种形式供选择。最后以一个数据实例进行了程序演示。

Standard deviation as a parameter to reflect average dispersion of every actual variable value and arithmetic mean. In the instrumentation, machinery, professional field information class, it occupies an important position. Therefore, a system of exclusively computing standard deviation with various approaches will provide great convenience ：for work in related fields. This article describes the standard deviation computing system based on VB.NET language development environment; it can use a variety of commonly used methods, calculate standard deviation of a set of parameters and other parameters, and it provides two forms to choose of input directly data and read the file. In the end, there is a data instance of the program demonstrate.
