Sample Size Template 1
Quantitative rationale: The primary analysis requires [n] analyzed units for [power/precision assumptions]; we will recruit [n2] allowing [x%] loss.

Start with structure, then replace every placeholder with information that is true, relevant, and natural for your context. These templates are intentionally skeletal so your final writing does not sound mass-produced.

How to personalize a template
A justified sample size follows from the study design and inferential goal, accounts for expected variability or information needs, anticipates attrition or unusable data, and distinguishes planned from achieved sample size.
- 1Choose the template closest to your actual purpose.
- 2Replace every bracketed field with specific information.
- 3Delete any sentence that does not belong in your situation.
- 4Read the result aloud for unnatural transitions or repeated phrasing.
- 5Verify names, dates, links, facts, and promises before sending or publishing.
Sample Size Template 2
Qualitative rationale: We will begin with [range] cases selected for [variation], then assess whether additional cases add materially new information.
Sample Size Template 3
Flow statement: screened [n] → eligible [n] → enrolled [n] → completed [n] → analyzed [n].
Sample Size Template 4
Sensitivity note: If [assumption] differs, the required sample changes from [n] to [n]; report this range rather than false precision.
