    Area of Science:

    • Statistics
    • Experimental Design

    Background:

    • Analyzing variance in two-way classification is crucial for understanding data heterogeneity.
    • Identifying homogeneous subsets of variances aids in robust statistical inference.

    Purpose of the Study:

    • To propose a novel multiple range procedure for identifying homogeneous subsets of variances.
    • To provide critical values and a practical example for the proposed method.

    Main Methods:

    • Development of a multiple range procedure tailored for variance subsets.
    • Specification of appropriate critical values for hypothesis testing.

    Main Results:

    • The proposed procedure effectively specifies homogeneous subsets of variances.
    • The provided critical values facilitate the application of the method.

    Conclusions:

    • The new multiple range procedure offers a valuable tool for variance analysis in two-way classifications.
    • The method enhances the ability to identify and interpret patterns of variance homogeneity.
