The power of an exact test refers to the probability of correctly rejecting the null hypothesis when it is false. Some synonyms for power include sensitivity, efficiency, and effectiveness. Sensitivity refers to the ability of a test to correctly identify positive cases. Efficiency refers to the ability of a test to use resources effectively and minimize errors. Effectiveness refers to the ability of a test to achieve its intended goals. Other potential synonyms for power in this context may include accuracy, precision, and reliability. Understanding variations in power across different tests and scenarios can be crucial for making informed decisions and interpreting statistical results.
