专家意见:N=1 animal was enrolled in each group. This is so small sample size. I understand the need to reduce as much as possible the number of animals included in such experimentation, but exactly for this reason a power analysis for sample size calculation must be provided. 译文:每组有 ...
Therefore, as consultants, we would like to recommend that our clients have an idea of what they would expect to be a scientifically meaningful difference before doing a power analysis to determine the actual sample size needed. Calculation of Statistical Power The power is a probability and it ...
Power analysis and sample size calculation are intensely debated topics in medical research. With increasing pressure on researchers, medical journals are demanding a priori power analysis or sample size calculation as an imperative part of a well-designed study. Consequently, study authors feel compelle...
