I am hoping for some advice regarding interpretation of  Fishers exact test
output.

I have some 3 x 2 contingency tables where the cell count is too small for
a Chi-square to be computed. In the usual instance where the cell counts
are large enough the residuals can be used to identify which associations
are statistically significant. In the example that follows, Fishers exact
test is employed, what criteria are used in in interpreting this reported
significant association - e.g is the association just between group 3 and
command.to.harm?


command.to.harm
group  n  y
     1    97  7
     2    28  5
     3    16  7


p-value = 0.006


Any assistance with this enquiry is appreciated,

regards

Bob Green
