Quantitative vs Qualitative Research: When to Use Each Method
Market research is one of the most powerful tools organizations can use to understand customers, evaluate opportunities, reduce risk, and make informed business decisions. However, selecting the right research methodology is critical to generating meaningful and actionable insights.
One of the most common questions businesses ask is whether they should use quantitative research or qualitative research.
The answer depends on the objectives of the study, the type of information needed, and the business decisions being supported. Both methodologies offer unique advantages, and many of the most successful research programs combine elements of both.
In this guide, we’ll explain the differences between quantitative and qualitative research, explore when to use each method, and discuss how Veridata Insights helps organizations choose the right approach for their market research needs.

What Is Quantitative Research?
Quantitative research focuses on collecting numerical data that can be measured, analyzed, and used to identify trends, patterns, and relationships.
Researchers use quantitative methods to answer questions such as:
- How many?
- How often?
- What percentage?
- What is the average?
- Is there a statistically significant difference?
Common Quantitative Research Methods
- Online surveys
- Telephone surveys
- Customer satisfaction studies
- Brand tracking research
- Market segmentation studies
- Product concept testing
- Polling research
Quantitative Research Example
A company surveys 2,000 customers and finds that 72% are satisfied with a recent product launch.
This numerical result can be analyzed and compared across customer segments or time periods.
What Is Qualitative Research?
Qualitative research focuses on understanding opinions, motivations, emotions, attitudes, and behaviors.
Rather than measuring responses numerically, qualitative research explores why people think and act the way they do.
Researchers use qualitative methods to answer questions such as:
- Why do customers behave this way?
- What motivates purchasing decisions?
- How do people perceive a brand?
- What challenges do customers face?
Common Qualitative Research Methods
- In-depth interviews
- Focus groups
- Online discussion boards
- Ethnographic research
- Customer journey interviews
- User experience studies
Qualitative Research Example
A focus group reveals that customers associate a brand with trust and reliability because of positive past experiences.
These insights help explain customer behavior in ways that survey data alone may not reveal.
According to the Market Research Society (MRS), both quantitative and qualitative research play important roles in helping organizations understand consumer behavior and support effective decision-making. Learn more at https://www.mrs.org.uk.
Key Differences Between Quantitative and Qualitative Research
Although both approaches aim to generate insights, they differ significantly in methodology and outcomes.
| Category | Quantitative Research | Qualitative Research |
|---|---|---|
| Purpose | Measure and quantify | Explore and understand |
| Data Type | Numerical | Descriptive |
| Sample Size | Large | Smaller |
| Analysis | Statistical | Thematic |
| Results | Generalizable | In-depth insights |
| Questions Answered | What, how many, how often | Why and how |
| Research Tools | Surveys, polls | Interviews, focus groups |
Key Takeaway
Quantitative research measures behavior, while qualitative research explains behavior.
When to Use Quantitative Research
Quantitative research is most effective when organizations need statistically reliable results from a larger audience.

Quantitative vs Qualitative Research Comparison Table
| Factor | Quantitative | Qualitative |
|---|---|---|
| Sample Size | Large | Small |
| Data Type | Numerical | Narrative |
| Statistical Analysis | Yes | No |
| Exploration of Motivations | Limited | Extensive |
| Generalizability | High | Lower |
| Research Speed | Faster | Slower |
| Cost Efficiency | Often Higher | Often Lower for small studies |
| Best For | Measuring outcomes | Understanding reasons |
Why Many Organizations Use Both Methods
Many successful research programs use a mixed-methods approach that combines quantitative and qualitative research.
For example:
Step 1: Qualitative Research
Conduct interviews or focus groups to explore customer perceptions and identify key themes.
Step 2: Quantitative Research
Survey a larger audience to measure the prevalence of those themes.
This approach provides both depth and scale.
Organizations gain a more complete understanding of their audiences and can make decisions with greater confidence.
