Sample Size Calculation
Sample Size Calculation for Thesis Research
Plan an appropriate respondent count before data collection. The calculation is based on your research design, population information, and other assumptions confirmed during scoping.
A good fit for

- Researchers responding to sample-size questions from a panel
- Projects that need the assumptions stated clearly
Confirmed deliverables
What is included
- Review of the study information needed for the calculation

- The resulting sample-size calculation
- An explanation of the assumptions used in the calculation
Before submitting
What to prepare
- Research design and main objective
- Target population and estimated population size, when known
- Sampling approach and respondent groups
- Any margin, confidence, power, or school requirement already specified
Academic integrity
Important boundaries
- There is no single sample-size formula that is correct for every study.
- A calculation is only as appropriate as the design choices and assumptions supplied.
- Recruitment constraints and nonresponse may require planning beyond the calculated minimum.

Frequently asked questions
Can you calculate a sample size if I do not know the population?
Possibly, depending on the research design and information available. State clearly what is known so the team can identify an appropriate approach or explain what must be decided first.
Is Slovin’s formula always the right method?
No formula is universally appropriate. The choice should follow the design, the analysis being planned, the available population information, and any institutional requirement.
Should I add respondents for possible nonresponse?
That may be appropriate, but it is a planning decision separate from the calculated minimum. Discuss expected nonresponse and recruitment limits when the service is scoped.
