Mean known be sensitive towards outlier and this problem will affect robustness power ANOVA. In study, modification was created using one type replace arithmetic namely trimmed mean. New approaches were obtained This study conducted based on simulation application real data. The performance modified then compared with classical terms Type I error rate. innovation enhances ability provide good control rates. findings favor better as ANOVATM.
