In statistical analysis, a power level of 0.80 (or 80%) is commonly recommended as it strikes a balance between being statistically rigorous and practical in terms of sample size and resource requirements. This level of power means there is an 80% chance of correctly rejecting a false null hypothesis (i.e., detecting an effect if there is one).
