WebNov 19, 2024 · An equally extreme outcome favoring the Control Group is shown in Table 12.5.2, which also has a probability of 0.0714. Therefore, the two-tailed probability is 0.1428. Note that in the Fisher Exact Test, the two-tailed probability is not necessarily double the one-tailed probability. Table 12.5.2: Anagram Problem Favoring Control Group. Webpointed out that sample size determination is a difficult process to handle and requires the collaboration of a specialist who has good scientific knowledge in the art and practice of medical statistics. Techniques for estimating sample size and performing power analysis depend mainly on the design of the study and the main measure of the study.
