WebbComparing fisher.test p values from the example above, two-sided is 0.272 but one-sided greater-than is 0.209. This means it's not symmetrical (.209 in upper tail and .063 in lower tail). So, I'm using the uncorrected one-sided fisher.test until I can find a mid-p corrected one-sided method. Alex G. Dec 11, 2014 at 14:11 Add a comment 1 Webb29 sep. 2024 · 2. There is no test statistic to report. Unlike a Chi-Square test of independence, Fisher’s exact test has no test statistic to report. Instead, we simply report the p-value of the test and note that we used Fisher’s exact test. This is a commonly used test, so it’s well known that there will be no test statistic included in the final report.
