Step 2. Perform an analysis of variance (ANOVA) for
number of plants (X) to get the sum of squares (Ex2)
values:

 (CF) = Correction Factor
 = (1310)2 / 24
 = 71504.17

 SST = Treatment sum of squares
 = {[(241)2 + (219)2 +...+ (224)2] / 4} CF
 = 561.33
 = (Ex2)trts

 SSB = Block sum of squares
 = {[(318)2 + (302)2 +...+ (324)2] / 6} CF
 = 372.50
 = (Ex2)blocks

 SStot = Total sum of squares
 = [(60)2 + (47)2 +...+ (62)2 + (61)2] CF
 = 1999.83
 = (Ex2)total

 SSE = Error sum of squares
 = SStot (SST + SSB)
 = 1999.83 (561.33 + 372.50)
 = 1066
 = (Zx2)error

Step 3. Perform the ANOVA for yield (Y) to get the Ey2
values:


CF = (95.67)2 / 24
 = 381.36


{[(19.43)2 +...+
8.47
(Ey2)treatments

{[(18.34)2 +...+
10.44
(Zy2)blocks


(16.09)2] / 4} CF




(29.51)2] / 6} CF
