From raw records to tables you can put your name on

Bharat Survey offers survey data analysis services for market research firms, CSR and NGO teams, academics and departments who have survey data, or are about to collect it, and need it cleaned, weighted, tabulated and interpreted properly. We work on data from our own fieldwork and on datasets you bring, and every transformation from raw file to final table is logged so a reviewer can retrace it.

  • Sampling design before fieldwork
  • Data entry for paper schedules
  • Cleaning with a written log
  • Weighting, tables and significance tests

Why analysis starts before fieldwork

Design

The quickest way to improve a survey's analysis is to involve the analyst while the sample is still on paper. We work out what the study needs to report, and for which groups, and build the sample from there: strata, clusters, sample size per reporting cell, selection method and the weights the design will need later.

What a sampling note covers

A short document your team and reviewers can check, written in plain language.

  • Target population and sampling frame, with its known gaps
  • Strata and allocation, including any oversampling
  • Clusters per stratum and interviews per cluster
  • Expected design effect and resulting margin of error
  • Replacement and non-response rules
  • How weights will be calculated

When the sample is already fixed

If fieldwork is done, we assess the achieved sample against the plan, explain what it can and cannot represent, and recommend weights or reporting limits rather than pretending the gaps are not there.

Common design questions

  • How many interviews per district?
  • Should we oversample a small group?
  • How many villages vs households?
  • What margin of error is realistic?
Processing

Five stages, each producing a file you keep.

  1. 01

    Intake and codebook check

    We compare the data against the questionnaire: variable names, value labels, skip patterns. Mismatches go into an intake note before anything is changed.

    Cleaning with a log

    Out-of-range values, broken skips, duplicates and inconsistent answers are resolved by written rules. Every change is logged with the rule, original value and new value.

    Coding open-ended answers

    Verbatim responses are coded into a frame agreed with you, with a second coder checking a sample for consistency.

    Weighting

    Design weights, non-response adjustment and, where justified, calibration to known totals such as Census population, with the effect on precision reported.

    Tables and analysis

    Banner tables with bases, significance testing, and deeper analysis where the question needs it: regression, segmentation or index construction.

Paper schedules

Paper is still common in some government and academic studies. Data entry done carelessly adds errors that no analysis can detect.

Entry screens that enforce the questionnaire

We build entry forms that mirror the schedule, with the same skips and valid ranges, so an operator cannot type an impossible value without a warning.

Schedules are logged in and out by ID, so none is entered twice or lost.

  • Range and skip checks
  • ID-based batch tracking
  • Operator-level error rates

Double entry and reconciliation

For studies that need it, a share of schedules or all schedules are entered twice by different operators and differences are resolved against the paper.

FAQ

Straight answers to the questions people ask most about this topic.

Can you analyse data collected by another agency?

Yes. Share the dataset, questionnaire and any sampling documentation. We start with an intake check and tell you what the data can support before any analysis, including gaps in the sample or skips that were not followed.

Which formats and tools do you work with?

Common formats such as CSV, Excel, SPSS and Stata files, and exports from ODK-based tools. Deliverables come in the format your team uses, along with the scripts so the work can be rerun.

What does survey data analysis cost?

It is quoted per project. Cost depends on dataset size, cleaning effort, number of tables and banners, open-ended coding volume and whether advanced analysis is needed. Send the questionnaire and a sample of the data for a quotation.

How is data kept confidential?

Access is limited to the named project team, personal identifiers are separated from analysis files where possible, and the data hosting location and retention period are stated in writing in the proposal.
