To be of real value, market research has to be cleaned of invalid responses, such as non-genuine answers and submissions from outside a required geographic region. While you can’t (yet!) put responses through a lie detector test, there are still many ways to identify rogue submissions.

Following the Quality Control tips below will help you catch responses that are deliberately or accidentally invalid. And, thanks to recent improvements to Nfield’s Quality Control feature, taking action is easier than ever.

Here are measures you can take to safeguard survey response quality, followed by a guide to using Nfield’s improved Quality Control feature.

Best practices for identifying invalid survey responses

Set clear data quality benchmarks
Establish predefined criteria for acceptable completion durations, location accuracy, and logical consistency within sets of answers. See below for examples.

Check completion durations
Check for questionnaires that have been completed within an unreasonably short time. For example, if a survey is estimated to take 10 minutes, any that are completed in under two minutes should be flagged for review.

Leverage location data
Verify that respondents are within the target geographical area. For example, if a CAPI survey delivers responses from Birmingham when the target area was London, those responses should be flagged for further review.

Monitor response patterns
Identify anomalies such as straight-lining (choosing the same answer for all questions), contradictory responses, or unusual answer distributions. For instance, if a respondent selects both “Strongly Agree” and “Strongly Disagree” for similar questions, their responses should be reviewed.

Use attention checks and red herring questions
Embed control questions to detect (unintentionally or deliberately) inattentive respondents. For example, a question could instruct, “Select ‘Strongly Agree’ as your answer for this question.” If a respondent fails this check, their survey submission can be flagged as potentially low quality.

Review open-ended responses
Ensure meaningful engagement by analyzing open-text answers. Responses like “asdasd” or “12345” indicate respondents are not making an effort to answer properly.

Combine automated and manual reviews
For optimum results and efficiency, use a mix of manual and automated Quality Control techniques. For example, automated tools can be developed to detect questionnaires that were completed too quickly, while researchers can manually verify the status of flagged responses.

Act fast on low-quality responses
Ensure unreliable responses are filtered out before finalizing data analysis. Removing inconsistent data promptly prevents derivation of misleading insights and improves overall research quality.

Discover Nfield’s enhanced Quality Control feature

With Nfield’s updated Quality Control feature, market researchers can drill down into each interview to see details such as responses, location, duration and other key insights. Any interviews that appear suspicious can easily be flagged for further quality control checks and possible removal.

• Detailed question responses – show how each respondent answered every question, making it possible to identify inconsistencies or suspicious patterns.

• Survey location data – makes it possible to verify whether survey responses satisfy geographical criteria. See Academy #57 for GPS Location Fix.
• Interview duration – reveals completion times, making it possible to identify responses that are likely to be of poor quality due to surveys being completed too quickly.
• Other key metadata – provides access to timestamps, respondent details and more in one centralized location.
• Flag for review – Researchers can flag specific interviews inside the questionnaire script for additional quality checks. Setting the system variable “TTInterviewQuality” to 5 assigns an interview with a “Needs to be checked” status. This is useful for flagging straight-liners (respondents answering too predictably) or speedsters (respondents completing the survey too quickly). Flagged interviews can then be reviewed directly on the Quality Control page without downloading data files.

How to use Nfield’s Quality Control feature

1. Navigate to the Quality Control page in Nfield.
2. Click on any interview to expand the details.
3. Review responses, location (CAPI only), duration, and key metrics.
4. Use the flagging feature inside the questionnaire script to mark responses that require further review.
5. Apply the best practices (described earlier in this article) to refine data collection strategies or optimize survey design.

NOTE: Nfield doesn’t currently include automated Quality Control tools. However, custom scripts for these can be inserted into Nfield.

GPS logging is a game-changer when it comes to improving accuracy, reliability and relevance of market research surveys. From conducting face-to-face interviews to mystery shopping and retail store auditing, GPS logging brings additional layers of insight that let you work smarter and deliver more meaningful results.

Here’s an overview of what GPS logging is, and how it benefits market research.

What is GPS logging in surveys?

GPS logging is the process of capturing and storing geolocation coordinates at the point where market research interviews are conducted. These coordinates are tied to the survey responses, providing precise geographical context.

GPS logging leverages existing GPS functionality in the smartphones and tablets used to record interview responses.

Why use GPS logging in market research?

1. Location verification reduces risk of fake responses

GPS logging provides a powerful means of validating survey data and assuring its integrity. It enables researchers to track exactly where fieldwork is being carried out, to ensure it’s taking place in the intended locations. For example, in mystery shopping or retail audits, GPS coordinates can confirm that interviewers actually visited the specified stores or locations. Using GPS logging thereby reduces the risk of fraudulent or fabricated data, which is the case when surveys are filled out remotely instead of at the designated site.

2. Enhanced location-specific insights

Because GPS logging enables researchers to map survey responses geographically, it also delivers insights into regional or location-specific trends. For example, a beverage company may discover that consumer preferences vary significantly between urban and rural areas, and this helps them fine-tune their distribution strategy.

3. Improved fieldwork management

For studies involving large-scale field teams, GPS logging enables real-time tracking of interviewer activity. This is helpful for ensuring full coverage of assigned areas, as supervisors can monitor progress and adjust fieldwork schedules dynamically to optimize efficiency.

4. Enriched insights through correlations with external datasets

GPS data can also be enriched with external geospatial datasets, such as demographics, traffic patterns, or weather conditions. This adds another dimension to market research insights, revealing correlations that might otherwise go unnoticed.

In summary, GPS logging enhances market research survey quality and efficiency in many ways, making the results even more valuable.

Utilizing GPS logging in Nfield surveys

GPS logging is easily applied in Nfield surveys via three different options:

• Location capture at interview start: verifies the location where questioning began.
• Location capture at interview end: verifies the location where the final response was entered.
• Continuous GPS tracking throughout interview: records location where each question is answered. This monitoring of movement throughout the interview provides deeper behavioral insights and goes further in preventing fraudulent responses.
