ESS = TSS – (BSS + tSS)
= 25.39 – (5.4 + 18.4) = 1.57

STEP 4.Divide each SS by its corresponding df to determine the:
BMS= BSS =5.4 = 1.8
Bdf 3
tMS=tSS = 18.41 = 4.5
tdf 4

EMS =ESS = 1.57 =0.131
Edf 12

STEP 5. Solve for the Computed F value by dividing the MS for each SV by
the EMS.
Fc for Block =BMS = 1.8 = 13.74
EMS 0.131

Fc for treatment =tMS= 4.6 = 35.11
EMS 0.131

STEP 6. Construct the ANOVA Table and enter all the computed values
CV = EMS X 100 = 0.131 X 100 = 8.7%
