Question

From the table, how much variation (SS) was accounted for by the blocking structure (2 decimal places):

df	SS	F value
Block	3	2.74	0.001
Treatment	14	42.95	0.001
Residuals	42	6.21	
Total	59	51.90

The question asks for the sum of squares (SS) attributed to the blocking structure, with results shown to two decimal places.
First, identify the SS value associated with the Block row in the table. The Block row lists df = 3, SS = 2.74, F value = 0.001.
Since SS represents the variation explained by each source of variation in ANOVA, the SS for Blocking directly answers how much variation is accounted for by the blocking structure.
Among the values in the table, the Block row’s SS is 2.74. Therefore, the amount of variation (SS) attributed to blocking is 2.74 (to two decimals).
For context, the other SS values are: Treatment 42.95, Residuals 6.21, and Total 51.90. These give a sense of how the total variation partitions among blocks, treatments, residuals, and the grand total.
