Quantitative Survey
Structured data collection used to measure patterns, frequencies, perceptions, preferences, behaviors, or outcomes across a defined population or sample.
Methodology
The Method Follows the Question.
EIRG does not force one method onto every problem. The research approach must be selected based on the research question, decision need, target population, geography, and analytical objective.
Start a Research ProjectResearch Design
Start with the decision need, then design the evidence path.
Good research design connects the question, population, geography, data source, field approach, analytical objective, and reporting need before data collection begins.
EIRG selects the combination of methods that best fits the problem instead of treating one method as the answer to every research need.
Quantitative Research
Measure patterns with structured data.
Quantitative approaches are useful when the research needs comparable measurements across a defined group, market, population, service experience, or program audience.
Qualitative Research
Understand meaning, experience, and the reasons behind responses.
Qualitative research helps explain how people understand an issue, why they respond in certain ways, and which contextual factors shape their experiences and decisions.
In-Depth Interview (IDI)
One-to-one conversations designed to explore experiences, motivations, interpretations, decision processes, and context in greater depth.
Focus Group Discussion (FGD)
Facilitated group discussions used to understand shared views, differences, language, reactions, experiences, and the reasons behind participant perspectives.
Observation & Field Study
Study what happens in the real setting.
Observation and field study are used when the research requires direct attention to environments, processes, behaviors, service conditions, access, interactions, or local context that cannot be understood fully through self-reported answers alone.
Observation & Field StudyMystery Shopping / Service Experience Study
Examine service delivery from the user perspective.
Mystery shopping and service-experience studies can assess how a service is delivered in practice, including customer journeys, access points, information quality, process consistency, and observable service standards.
Mystery Shopping / Service Experience StudyDesk Research & Data Analysis
Build insight from existing evidence.
Desk research and data analysis examine existing documents, reports, administrative information, published datasets, prior studies, and other relevant evidence to answer research questions or strengthen primary research design and interpretation.
Desk Research & Data AnalysisMixed Methods Research
Combine measurement with explanation.
Mixed methods bring quantitative and qualitative evidence together when one form of data alone is not enough to answer the research question clearly.
Quantitative helps us understand “how much”. Qualitative helps us understand “why”.
Geographic & Segment Analysis
See where patterns differ and for whom.
Geographic and segment analysis helps identify meaningful differences across locations, population groups, customer types, service areas, demographic profiles, or other research-relevant segments.
Geographic & Segment AnalysisQuality Control
Quality is part of the research process, not an afterthought.
Data is reviewed systematically before analysis so that the final dataset is fit for the intended research purpose.
- 01Completeness Check
- 02Consistency Check
- 03Validation
- 04Cleaning
- 05Final Dataset
Every dataset is reviewed for completeness, consistency, and quality before analysis.
Research Ethics & Confidentiality
Protect people, information, and the credibility of the research.
EIRG treats ethical practice, confidentiality, appropriate data use, and transparent interpretation as part of credible research delivery.
- Respondent confidentiality
- Client confidentiality
- Appropriate use of research data
- Evidence-based interpretation
- Relevant methodological transparency
- Commissioned research may remain confidential
Start a Research Project
Choose the method after we understand the question.
Tell us what decision, population, market, program, or issue you need to understand. EIRG can help shape a practical research approach around that need.
