Pooled StDev = 20.35 40 60 80

Fisher's pairwise comparisons

Family error rate = 0.276
Individual error rate = 0.0500

Critical value = 2.014

Intervals for (column level mean) - (row level mean)

Kesimpulan nilai P (0.000) < Alpha (0.05) maka kelima macam limbah tersebut menghasilkan hasil yang berbeda nyata <>
