Continuity Correction for Fisher's Exact Probability Test.
Overall, John E.
Journal of Educational Statistics, v5 n2 p177-90 Sum 1980
Fisher's exact probability test is severely conservative when interpreted with reference to conventional alpha levels due to the discontinuity of the sampling distribution for 2 x 2 tables. An adjustment of the cell frequencies is proposed that results in a correction for continuity with appropriate alpha protection and increased power. (Author)
