Flagging and Fixing Mid-Field Data Quality Issues Automatically

How DataDiggers Ensures Real-Time Insight Integrity with Correlix’s Auto-QA on Brainactive Sample Delivery

The Challenge: Quality Risks in the Field

In fast-paced market research environments, speed-to-insight is critical—but never at the expense of data quality. For studies using large-scale respondent input, traditional quality assurance measures often happen after data collection, when it's too late (or too costly) to fix issues like inconsistent answers, bots, duplicates, or disengaged participants.

One of our long-term global brand clients approached us with a clear pain point:
“How can we ensure that real-time survey responses are clean, consistent, and meaningful—before they impact final results?”

They were particularly concerned with mid-field data corruption, where response quality begins to degrade midway through the project, often due to fraudulent participants or inattentive respondents slipping through early-stage screens.

The Solution: Real-Time Auto-QA with Correlix + Brainactive

To solve this, DataDiggers deployed a layered, automated data integrity system by integrating Correlix's statistical and machine learning-based auto-QA engine directly into Brainactive’s sample delivery workflow.

Correlix, our synthetic data and bias-correction solution, was fine-tuned to process incoming survey responses in real time. Sitting on top of Brainactive—our proprietary DIY research platform—it flagged and corrected issues while fieldwork was live, ensuring that only high-integrity data made it into the final results.

Key Features of the Solution:

• Live Response Monitoring: Every answer was evaluated by Correlix’s algorithms for patterns indicating low engagement (e.g., speeding, straight-lining, meaningless text).
• Behavioral Anomaly Detection: Based on historical and synthetic benchmarking, Correlix flagged outliers not just statistically, but behaviorally—catching what traditional rules-based systems miss.
• Dynamic Re-Targeting: When low-quality respondents were flagged mid-survey, Brainactive auto-replenished them in real time with verified replacements, ensuring sample consistency without delays.

Seamless Reporting Integration: Results were reflected live in Brainactive’s dashboard, allowing the client to track survey quality visually, with real-time filters and auto-generated flags.

What Changed for the Client:

• They no longer had to “clean up” data post-field, saving internal analytics time and costs.
• They gained live quality assurance visibility, enhancing internal stakeholder trust in research findings.
• Mid-field data anomalies—such as contradictory or nonsensical open-ends—were caught before they polluted the dataset.
• Project timelines shortened by an average of 1.5 business days.

Why It Worked: A Layered Approach to Trustworthy Data

At DataDiggers, we believe data quality should be embedded—not bolted on. This success stemmed from a multi-layer strategy:

1. Human-verified, deeply profiled respondents via MyVoice and trusted partners
2. Best-in-class fraud detection tools at entry: IPQS, GeoIP, digital fingerprinting, deduplication, and reCAPTCHA
3. In-survey AI and ML-powered quality evaluation using Correlix
4. Seamless delivery, replenishment, and QA reporting through Brainactive

This layered approach makes manual cleaning almost obsolete, allowing our clients to focus on decisions, not data wrangling.

A Note from the Client

“We were impressed with how issues were caught and corrected mid-field. There was no need to halt the study or re-launch quotas. Everything just worked in the background—and the final data was clean, actionable, and fast.”
