Derivation of Expected Mean Squares (EMS) Using Venn Diagram by the Type of Experimental Design

실험설계 유형별 Venn Diagram을 이용한 EMS 도출

The study presents an efficient design method of Venn Diagram that can be used when implementing the quality design of experiments based on generalizability theory. The paper examines four mixed and combined models that are designed by fixed factor, random factor, crossed factor and nested factor. The models considered in this research are $A^*{\times}B^*{\times}C$, (B: $A^*$)${\times}C$, $A{\times}B{\times}C$ and (B: A)${\times}C$.
