A power of .40 indicates that there is only a 40% chance of obtaining a significant result, which is a relatively low probability. As an IACUC, our role is to ensure that animal studies are designed with appropriate statistical power to minimize the number of animals used and to avoid conducting studies that are unlikely to yield meaningful results. Therefore, a study with a power of .40 may not be ethical or meaningful and should not be approved.
