A survey method is the way you collect answers — the channel between your questions and your respondents. It is different from the type of survey (what it is about and for) and from the question types you use. Pick the wrong method and even a perfect questionnaire reaches the wrong people, or no one at all. Here are the main survey methods, with their strengths and limits, and how to choose.

The main survey methods

• In-person (CAPI). A trained enumerator interviews face to face on a device. Highest quality and reach, works regardless of literacy or connectivity, and lets you verify with photos and GPS. Essential for rural India — see CAPI surveys.
• Telephonic (CATI). Interviews by phone from a command centre. Fast and geographically wide, good for shorter studies and follow-ups — see CATI surveys.
• Online / web. A self-completed link. Cheap and instant, but only reaches digitally connected, literate respondents — it misses most of offline Bharat.
• Paper (PAPI) & mail. Printed forms filled by hand. Low-tech and still used in some settings, but slow, error-prone and heavy to digitise.
• Mobile & SMS. Short questionnaires pushed to phones. Useful for quick pulses, limited for anything long or complex.
• Observation. The enumerator records what they see — shelf stock, assets, conditions — rather than asking. Common in retail audits and asset verification.
• Mixed-mode. Combining methods — say in-person for rural and phone for urban — to balance reach, speed and cost. Most large studies end up here.

Quantitative vs qualitative methods

Survey methods also split by the kind of data they produce. Quantitative methods use mostly closed questions to produce numbers you can count and compare at scale — the bulk of commercial and field surveys. Qualitative methods use open questions, in-depth interviews or discussions to capture the “why” in people’s own words. Many studies combine both: a large quantitative survey with a smaller qualitative layer for depth.

How to choose a survey method

Work through five questions. Who and where are the respondents — connected and urban, or offline and rural? What reach do you need — a city, a state, all of India? How fast — a quick pulse or a thorough study? What budget — online is cheapest per response, in-person the most reliable? What data quality do the stakes demand? For a deeper head-to-head of the three field methods, see the guide to CAPI vs CATI vs PAPI. The method is also one layer of the wider data collection decision.

Why in-person still wins in Bharat

Most of India is not reachable by a web form. A large share of respondents are offline, speak a regional language, and will not answer an unknown number at length. For anything that drives money or a claim — distribution, welfare, impact, compliance — the reliable method is a trained person, in the local language, face to face, capturing a geo-tagged, photo-verified response. Online and SMS have their place for quick, connected audiences; they are not a substitute for fieldwork where it matters.

What makes a method reliable

The method is only as good as how it is run. A reliable survey needs a sound sample, trained and verified enumerators, and quality control at every step — geo-tag and time-stamp on each response, photo evidence, and AI checks that flag duplicates and contradictions before the data reaches your dashboard. Method plus discipline is what turns answers into data you can defend.

Frequently asked questions

The bottom line

The survey method is the bridge between your questions and your respondents. Online and SMS are fast and cheap but reach only the connected; in-person is the most reliable and the only one that truly covers Bharat; most real studies mix methods. Choose by who you need to reach and how much the data matters — and run it with sampling, trained people and quality control behind it. Anaxee runs the field methods across India so the data comes back clean.
