Multi-layer verification checks, digital fingerprinting, and pattern audits to ensure 100% human, trustworthy data.
Decisions backed by bad data are worse than decisions made with no data. GPRS applies enterprise-grade Data Quality Assurance processes to protect our clients' research investments. Our technology stack and manual verification processes screen out bots, duplicate entries, speeders, and insincere responders, ensuring every data point comes from a verified respondent.
Analyzing browser and device attributes (hash values, canvas configs) to detect and block multiple submissions from the same user.
Verifying IP locations in real-time, blocking public VPNs, proxy servers, and routing links originating outside target boundaries.
Identifying speeders using completion times, flagging flat-liners (straight-lining matrix tables), and checking open-ends for gibberish.
Auditing interviewer-led CAPI files using GPS validation coordinates, time stamps, and random voice back-checks.
Validating open-access survey links that are vulnerable to automated bot submissions and duplicate records.
Securing absolute data integrity for high-stakes product updates or investment choices.
Ensuring interviewer compliance and validating coordinates for in-person household surveys.
Data Quality Assurance is built into our data collection services. We apply automated Javascript modules to **CAWI** online forms to track device attributes in real-time. For face-to-face **CAPI** fieldwork, we use built-in mobile validation checks (GPS coordinates, time-interval audits) and follow up with manual phone/audio back-checks to confirm interviewer compliance.
We write quality checks (speed traps, red herring questions, canvas check scripts) directly into the survey programming code.
Our server-side algorithms block duplicates and screen out VPNs before they can access the questionnaire.
Our data processors inspect the complete database, running pattern audits to find and flag straight-liners.
We remove flagged records, replace them with fresh clean sample, and compile the final quality audit report.
Detailed summary of screen-out counts, bot blocks, and data cleaning decisions.
Cleaned response file (SPSS/CSV) containing only genuine, verified respondent records.
A formal certificate verifying compliance with ISO 27001 data standards.
