Reader intent

Who this guide is for

Three readers arrive here with different problems. Each should be able to act on this page without reading all of it.

Buyers running a vendor call
Questions that reveal whether an agency has actually run quantitative surveys at your scale.
Procurement scoring proposals
A way to score the answers rather than the presentation.
First-time commissioners
What good answers sound like, so you can tell them from merely fluent ones.

The 10 questions

Do you run fieldwork in-house in my cities?
How do you verify interviews?
How will you design the sample?
Which languages do you work in?
How do you handle translation?
How is data secured, and are you DPDP compliant?
Who leads the project day to day?
Who writes the report?
What exactly will I receive? (e.g. data tables, dashboards, significance testing)
Can I see a sample report?

What goes wrong

Common mistakes in quantitative surveys

Most disappointing quantitative surveys studies fail for reasons that were visible in the design, not in the fieldwork. These are the ones we see most often, and what to do instead.

01
Choosing the sample size from the budget
Start from the precision the decision needs. A ±4% margin of error at 95% confidence takes roughly 600 interviews, and halving that error quadruples the cost — better known before you quote.
02
A sampling frame that does not represent the universe
Mall intercepts standing in for a city, or a customer database standing in for a category, produce a confident number about the wrong population.
03
A questionnaire that outlasts the respondent
Past 25 minutes, straight-lining and drop-out rise sharply. Cut the grid matrices before you cut the sample.
04
Weighting applied to rescue a broken field
Weights correct small imbalances. They cannot create respondents who were never interviewed, and heavy weights inflate the real margin of error.
05
A questionnaire nobody piloted
Routing errors, ambiguous scales and a 35-minute runtime are cheap to find in a 30-interview pilot and expensive to find in the full dataset.
06
Fieldwork without an audit trail
GPS tags, timestamps, audio snippets and back-checks are what let you defend a finding when a regional team disputes it. Specify them in the contract.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a quantitative surveys project. Most of it costs nothing, and it saves the two weeks a re-field would take.

1
Define the universe and the sampling frame in one paragraph before anything else is written.
2
Compute the sample from the margin of error the decision needs, not from the budget available.
3
Set quotas against a defensible external benchmark and monitor them daily in field.
4
Pilot 30 interviews, check the routing in the data file, then release full field.
5
Back-check 20% of interviews, GPS-tag completions, and fix the weighting scheme before analysis.
6
Agree the minimum reportable base before fieldwork, and hold the line in the tables.
7
Agree in writing who acts on each finding, and by when, before the debrief ends.
