Analysis of Covariance on The Randomized Plot Factorial Experiment Design

Abstract

This study isconducted in order to determine the effectiveness of the analysis of variance andcovariance on the randomized plot factorial experiment design for this purpose, comparative analysis of covariance analysisof variance tries to explain, while the created artificial dataset applying to randomized plot factorial experimentdesign respectively. Analysis ofcovariance is an analysis which consists of analysis of variance and regressiontechnique used together. Although the application of this technique consistsof different experiment design analysis of covariance can beapplied to all experimental design. This analysis usedby dividing non-homogeneous materials to sub-blocks or a co-variable (concomitant variable-covariates) toobtain more reliable results and experimental design toincrease sensitivity of experimental design. In thisstudy, in all experimental design covariates error varianceratio was determined that lower values compared to analysis of variance.The decrease of error variance ratio is significant in terms of increasingreliability of findings.
