When To Use Fisher ’ s Exact Test

چکیده

Six Sigma practitioners occasionally conduct studies to assess differences between items such as operators or machines. When the experimental data are measured on a continuous scale (measuring nozzle diameter in microns, for example), a procedure such as “Student’s” two-sample t-test may be appropriate. When the response variable is recorded using counts, however, Karl Pearson’s test may be employed. 2 χ 2

Exact Permutation Algorithm for Paired Observations : The Challenge of R . A . Fisher

Abstract: The major handicap of permutation test is the logical and computational requirement necessary to develop and implement the exact permutation scheme. This study provides an algorithm that systematically enumerates all the distinct permutations of the paired observations in an experiment without the possibility of repeating any of the permutations. The permutation algorithm presented co...

Conscious Sedation Procedures Using Intravenous Midazolam for Dental Care in Patients with Different Cognitive Profiles: A Prospective Study of Effectiveness and Safety

The use of midazolam for dental care in patients with intellectual disability is poorly documented. This study aimed to evaluate the effectiveness and safety of conscious sedation procedures using intravenous midazolam in adults and children with intellectual disability (ID) compared to dentally anxious patients (DA). Ninety-eight patients with ID and 44 patients with DA programmed for intraven...

Non-English speaking background patients in a predominantly English-speaking region may be more likely to present with a dementia other than Alzheimer’s disease

Information on 54 patients was retrospectively collected to compare the presentation trends of cognitive disorders in those of non-English speaking background (NESB) to English speaking background (ESB) attending an Australian memory clinic that extensively uses fluorodeoxyglucose positron emission tomography (FDG PET) in the diagnosis of cognitive concerns. NESB patients were less likely to be...

Conditional versus Unconditional Exact Tests for Comparing Two Binomials

There are two fundamentally different exact tests for comparing the equality of two binomial probabilities – Fisher’s exact test (Fisher, 1925), and Barnard’s exact test (Barnard, 1945). Fisher’s exact test (Fisher, 1925) is the more popular of the two. In fact, Fisher was bitterly critical of Barnard’s proposal for esoteric reasons that we will not go into here. Notwithstanding Fisher’s reserv...
