What you get with this Offer
I will conduct a formal statistical power analysis and calculate the required sample size for your study — using G*Power, R (pwr package), or Python (statsmodels) — covering power calculation for your specified test family, effect size justification from prior literature, sensitivity analysis showing power across a range of sample sizes, and a written power analysis report suitable for inclusion in a grant application, ethics submission, or dissertation proposal. Underpowered studies are the most common form of resource waste in quantitative research — they consume participant time and researcher budget to produce inconclusive results; overpowered studies unnecessarily expose more participants than required. The correct sample size requires a formal power analysis, not a rule-of-thumb guess.
The analysis covers test selection for your design, effect size specification with literature justification, alpha level selection, target power (typically 0.80 or 0.90), required N calculation, sensitivity plot showing achieved power across N values, and a power analysis write-up in the format required by your funder, ethics board, or institution.
Designed for researchers at the grant application or study planning stage who need a formal, documented power analysis.
