Step 1

(a)

The SSBL represents the block sum of the squares.

The source of variation for the block sum of squares is the variation among the sample means for the blocks.

The defining formula for SSBL is,

Step 2

(b)

The SSE represents the error sum of the squares.

The source of variation for the error sum of squares is the variation within the samples for the treatments with the variation due to blocks removed.

The defining formula for SSE is,

Step 3

(c)

The SSTR represents the treatment sum of the squares.

The source of variation for the treatment sum of squares is the vari...
