WebFeb 16, 2024 · High power in a study indicates a large chance of a test detecting a true effect. Low power means that your test only has a small chance of detecting a true effect or that the results are likely to be distorted by r andom and systematic error. Power is mainly influenced by sample size, effect size, and significance level.
