I always thought, SPSS would compute "Fisher's Exact Test" equivalant to the Freeman-Halton-Test. But this doesn't seem to be so.

Following data example:

line A B Sum
1 3 0 3
2 1 3 4
3 3 7 10
Sum 7 10 17


SPSS result: p=0,152

Chi-Square Tests
        Value df Asymp. Sig. (2-sided) Exact Sig. (2-sided) Exact Sig. (1-sided) Point Probability
Pearson Chi-Square 4.635a 2 .099 .152
Likelihood Ratio 5.783 2 .055 .152
Fisher's Exact Test 4.194 .152
Linear-by-Linear Association 3.602b 1 .058 .070 .055 .043
N of Valid Cases 18
a 5 cells (83.3%) have expected count less than 5. The minimum expected count is 1.33.
b The standardized statistic is 1.898.

But the Freeman-Halton p-Value should be p(A) = p(B) = 0.07229535170711625
