Hi. Thanks for your great efforts. I performed Fisher's exact test in SPSS, on a sample of 141 diabetic patients who have diabetic foot and I wanted to explore if there is an association between smoking levels on the rows side (nonsmoker, smoker, exsmoker) and diabetic foot prognosis on the columns side (No amputation, Amputation). I had the data in a 3 by 2 table, and I got SPSS output table showing the following numbers: first a value of 1.791 on the left side adjacent to "Fisher's exact test" sentence and I wonder what does it represent? and how is it calculated. second: a P value in the same row (0.454). third: a value named "The standardized statistic is -1.042." in the notes below the table, and I wonder what does it mean? and how is it calculated?
Interestingly, on the same sample of 141 diabetic patients, when I wanted to explore the association between diabetes mellitus type on the rows side (type 1, type 2) and diabetic foot prognosis on the columns side (No amputation, Amputation), I got SPSS output table showing empty cell adjacent to "Fisher's exact test" sentence on the left side. and a P value in the same row (0.720) and the term "The standardized statistic is -0.339." in the notes below the table mean. I wish if I could upload an image showing these results better than words.
