Data Cleaning & Management research service by IGREC

Service overview

IGREC converts raw research data into secure, consistent, and analysis-ready datasets. We document every transformation and protect the relationship between raw, cleaned, and final files.

Direct answer

Data cleaning and management services organise, validate, secure, and document research data. IGREC resolves structural errors, applies approved rules, creates codebooks, and controls versions. Analysts receive a reliable dataset with a clear audit trail.

Research teams needing secure, documented, reproducible preparation of survey or administrative data.

Tailored support

A service designed around the decision and field reality.

The scope connects research questions, methods, participants, operations, quality controls and final use.

Decision valueWhat this service helps you decide

Raw data often contains duplicates, inconsistent codes, missing identifiers, unit problems, impossible values, and version conflicts. Uncontrolled editing can create new errors or erase evidence.

IGREC uses scripted and documented workflows. We preserve untouched raw data, apply repeatable cleaning rules, generate review outputs, and separate identifying information from analytical files.

Expected outcomesWhat IGREC delivers
  • Consistent variables, formats, labels, and identifiers.
  • Resolved duplicates, merge problems, and coding conflicts.
  • Secure separation of personal and analytical data.
  • Reproducible processing from raw to final datasets.
  • Clear documentation for analysis, archiving, and handover.
Best suited toWho this service supports

This service supports household studies, enterprise surveys, RCTs, longitudinal research, mixed-methods studies, administrative-data projects, GIS datasets, and programme monitoring systems.

How IGREC delivers the service

A controlled process from mobilisation to handover.

01Secure the raw data.

We create controlled storage, access rules, backups, and immutable source copies.

02Profile the dataset.

We review structure, missingness, uniqueness, ranges, labels, and relationships.

03Apply approved rules.

Scripts standardise values, resolve duplicates, construct IDs, and prepare derived variables.

04Validate transformations.

We compare record counts, distributions, merges, and critical variables before approval.

05Deliver documented data.

We provide clean files, codebooks, processing scripts, logs, and version notes.

Typical deliverables

A documented handover your team can use.

  • Raw-data archive structure
  • Cleaning and management plan
  • Reproducible cleaning scripts
  • Clean and de-identified datasets
  • Codebook and data dictionary
  • Version log and data handover note

Why clients choose IGREC

Rigour connected to local implementation knowledge.

IGREC designs data management around future use. Variable names, identifiers, labels, units, dates, and merge keys support analysis rather than creating avoidable repair work.

We also apply least-access principles. Sensitive identifiers remain available only to authorised roles and only for approved purposes.

Relevant IGREC experience

Evidence from related assignments.

IGREC's portfolio includes datasets covering firms, workers, households, land parcels, health measurements, administrative tax records, GPS locations, and repeated survey rounds. These data types require disciplined cleaning, merging, documentation, and security.

Frequently asked questions

Practical answers before scoping begins.

Will IGREC change values that appear incorrect?

Only under approved rules and with documentation. Some anomalies remain flagged rather than altered when evidence is insufficient.

Can you merge survey and administrative data?

Yes, when identifiers, permissions, security, and data-sharing agreements support a valid merge.

Which file formats can you deliver?

Delivery can include common statistical, spreadsheet, text, and spatial formats based on the client's workflow.
