Every thesis group hits the same wall: the questionnaire is approved, and now you need a few hundred real people to answer it — not just your blockmates. Here are your realistic options, how many respondents you need, and how to defend your sample in front of the panel.

For many undergraduate and graduate studies, a mix works best: a panel for the bulk of responses, plus face-to-face for groups that are hard to reach online.

How many respondents do you need?

Most Philippine theses use Slovin’s formula:

n = N ÷ (1 + N × e²) — where N is the population size and e is the margin of error (usually 0.05).

Example: a population of 10,000 with a 5% margin of error gives 10,000 ÷ (1 + 10,000 × 0.0025) = 10,000 ÷ 26 ≈ 385 respondents.

A few honest caveats worth knowing before your defense:

  • Slovin’s formula assumes simple random sampling. With an online panel or convenience sample, say so in your methodology.
  • For very large or unknown populations, the answer levels off near 400 at a 5% margin of error.
  • Ask your adviser which approach your department expects — some prefer a power analysis or Cochran’s formula.

Ethics and the Data Privacy Act

  • Get informed consent on the first screen: who you are, the purpose, how long it takes, that participation is voluntary and answers are confidential.
  • Collect only what you need. In the Philippines, the Data Privacy Act of 2012 (RA 10173) covers personal information you collect. If you don’t need names, emails or phone numbers, don’t ask.
  • Check if you need ethics review. Many universities require a research ethics board clearance for studies involving people.

Make your questionnaire panel-ready

Using Ask Kita for your thesis

Ask Kita sends your survey to verified adult members in the Philippines and the rest of Southeast Asia:

  • Target by country, age range, gender and postal area.
  • Quality checks built in: an attention check and a speed check reject careless answers automatically, and you can flag a bad response within the review window for a refund.
  • Privacy by design: you see aggregated results and answers, never respondents’ identities or contact details — which also simplifies your privacy section.
  • Prepaid, per response. See the current rate card; unspent budget stays in your balance.

A limitations paragraph you can adapt

Respondents were recruited through an opt-in online panel of adults in [country]. Although quotas were applied for [age/gender/region], the sample is non-probability and may under-represent people with limited internet access. Results should therefore be generalised with caution.
