符合正态分布的计量资料,可以使用Ｆ检验或Ｂａｒｔｌｅｔｔ检验来判断两样本或多样本所代表的总体方差是否齐性。对于非正态分布的资料或尚不能确定其分布类型的资料,可以使用本检验来判断所比较的总体方差是否有差异。应用条件要求所比较的样本为相互独立的计量资料的随...
To meet the normal distribution of measurement data, you can use the F test or Bartlett test to determine whether the overall variance represented by two or more samples is homogeneous. For non-normally distributed data or data for which the distribution type cannot be determined, this test can be used to determine if there is a difference in the overall variance compared. The application conditions require that the samples to be compared are independent of each other’s measurement data.
