Explanation of Solution

Table -1 shows the 3 treatments as follows:

Treatment
123
7128
1089
121613
9136
121011

SST (Total) can be calculated as follows:

SS(Total)=j =1k i =1b(xijx¯¯)2=((710)2+(1010.4)2(12+10.4)2+(910.4)2+(1210.4)2+(1210.4)2+(810.4)2+(1310.4)2+(1010.4)2+(810.4)2+(910.4)2+(1310.4)2+(610.4)2+(1110.4)2)=99.6

SST can be calculated as follows:

SST=j =1kb(x¯[T]jx¯¯)2=(5(1010.4)2+(11.810.4)2(9.410.4)2)=15.6

SSB can be calculated as follows:

SSB=j =1kk(x¯[B]jx¯¯)2=(3(910.4)2+(910.4)2+(13.710.4)2+(9.310.4)2+(1110.4)2)=48.3

SSE can be calculated as follows:

SSE=SS(Total)SSTSSB=99.615.648.3=35.7

Thus. The value of SSE is 35.7.

Explanation of Solution

SST (Total) can be calculated as follows:

SS(Total)=j =1k i =1b(xijx¯¯)2=((710)2+(1010.4)2(12+10.4)2+(910.4)2+(1210.4)2+(1210.4)2+(810.4)2+(1310.4)2+(1010.4)2+(810.4)2+(910.4)2+(1310.4)2+(610.4)2+(1110.4)2)=99.6

Thus, the value of SS (Total) is 99.6.

SST can be calculated as follows:

SST=j =1kb(x¯[T]jx¯¯)2=(5(1010.4)2+(11.810.4)2(9.410.4)2)=15.6

Thus, the value of SST is 15.6

SSE can be calculated as follows:

SSE=SS(Total)SSTSSB=99.615.6=84

Thus. The value of SSE is 88.

(c)

To determine

Explain the way in which SS (Total) remains the same for both experimental designs.

(c)

Expert Solution
Check Mark

Explanation of Solution

From the estimation result, the variation between all the data is the same for both designs.

(d)

To determine

Explain the way in which SST remains the same for both experimental designs.

(d)

Expert Solution
Check Mark

Explanation of Solution

From the estimation result, the variation between treatments is the same for both designs.

(e)

To determine

Explain the way in which SSB+SSE is a part that is equal to SSE.

(e)

Expert Solution
Check Mark

Explanation of Solution

SSB + SSE is a part that is equal to SSE because the randomized block designs divide the sum of squares for error in the one – way analysis of variance into two parts.
