Modification of Fisher-Hayter Test

Abstract

Pair wise comparison are applied to answer which group differs when the null hypothesis in ANOVA test is rejected. This study modified the conventional Fisher-Hayter test to test the significant difference between the means when ANOVA test is significant. The conventional Fisher-Hayter test use MSE due to error while the modified Fisher-Hayter test use MSE due to treatment with different degrees of freedom. The result from modified Fisher-Hayter test are then compared with Fisher least significant difference, conventional Fisher-Hayter test and Tukey Honest Significant Different test. The result reveals that the modified Fisher-Hayter test showed comparable performance compared to the conventional Fisher-Hayter test and can be used as alternative of the pairwise comparison procedures.
