something wrong for the matched pair data?

[cwu <cwu@fcu.edu.tw>]

Hi there,

 

The below data set is from Box, Hunter, and Hunter,

 

boy material A    material B

1    13.2(L)            14.0(R)

2    8.2(L)                8.8(R)

3    10.9(R)            11.2(L)

4    14.3(L)            14.2(R)

5    10.7(R)            11.8(L)

6    6.6(L)               6.4(R)

7    9.5(L)              9.8(R)

8    10.8(L)            11.3(R)

9    8.8(R)             9.3(L)

10    13.3(L)        13.6(R)

 

L = left

R = right

 

I used

108.5^2/10+108.2^2/10-216.7^2/20

to have the SS for R/L

the answer = 0.0045

BUT

this does not agree with aov function in S, R, and MINITAB (0.1069)

 

What is wrong?

 

Thanks for any help.
