一种基于科学计算器的方差分析计算方法

A New Protocol of Analysis of Variance Based on Scientific Calculator

利用科学计算器直接计算出总标准差和总方差以及处理标准差和处理方差,然后用方差乘以自由度得到二者的平方和,再根据平方和公式计算出误差的平方和及方差。该方法在计算程序上比传统方法更简便,可用于统计计算和教学。

The population standard deviation and variance, the treatment standard deviation and variance can be readily obtained on the scientific calculator; and the total sum of square and the treatment sum of square can be calculated by muhiplying their degrees of freedom, then the sum of square for error can be obtained by deducting the former two, and the variance for error by dividing by its degree of freedom. The new protocol is more straight -forward than traditional one and can be applied to statistic computation or statistics teaching.
