Power calculations can be performed using statistical software or specific power calculation tools. Hereâs a general approach:
1. Define the Research Question: Clearly state the hypothesis and the expected effect size. 2. Determine the Significance Level and Power: Decide on the acceptable levels for α and 1-β. 3. Estimate Variability: Use previous studies or pilot data to estimate the variability in your data. 4. Calculate Sample Size: Use the chosen software or tool to input these parameters and compute the required sample size.
