When researchers come to the point of choosing a methodology for their research. They get confused between the two methods. The question at the back of their mind is, do I need to tell my findings in numbers or through people’s experiences? At this stage, it becomes necessary to understand the difference between qualitative vs quantitative research and how each of these methods can complement your research study more.
Picking the right method is necessary because it impacts your findings, the way you collect data, and how the results of your research can be applied. In this blog, we will explain the key difference between these two methods, their advantages and disadvantages, with a qualitative dissertation example.

Understanding the Two Research Approaches
The two research approaches at their base are used for different purposes. Qualitative studies are used to understand the why behind behaviors, decisions, and experiences. And this “why” is mostly answered through interviews, focus groups, and observations, which the researchers explain in words. This type of method reveals the themes and patterns that cannot be done only with numbers.
Whereas, quantitative research is to explain “what” and “how much.” They capture the answers to the “what” and “how much” through measurable information, which is collected through surveys, questionnaires, and tests. This type of method reveals the percentages and trends that can be generalized to larger populations.
Core Differences You Should Know
| Feature | Qualitative Approach | Quantitative Approach |
| Focus | Meanings, motivations, experiences | Measuring variables and trends |
| Question Type | “Why” or “how” | “What,” “how many,” “how much” |
| Approach | Exploratory | Conclusive |
| Data Sources | Interviews, focus groups, observations | Surveys, experiments, tests |
| Analysis | Narrative, thematic, interpretive | Statistical, numerical, objective |
| Outcome | Patterns, insights, understanding | Trends, correlations, measurable proof |
| Generalizability | Context-specific | Applicable to larger populations |
This quick table here has narrowed down the information about these two studies at a single glance. Below, we will explain qualitative vs quantitative research methods in detail.
Types of Quantitative and Qualitative Research Methods
Each research method has several techniques that you can choose according to the study’s objective.
Qualitative Techniques:
- In-depth Interviews: One-on-one discussions to ask about people’s experiences.
- Focus Groups: a conversation with a group of more than three to uncover shared experiences.
- Observation: observing behavior in natural settings.
- Content Analysis: Reviewing different books, texts, or media to find patterns and comparisons in a systematic way.
- Ethnography: living in a culture you want to study deeply.
Quantitative Techniques:
- Structured Surveys/Questionnaires: to collect data through the responses gathered from questions and surveys.
- Experiments: To experiment in a controlled setting by changing the variables.
- Tests and Assessments: To give a T-test to measure and compare performance, skills, or knowledge.
- Secondary Data Analysis: using existing data such as books, novels, texts.
- Structured Observation: to observe behavior in controlled settings.
These techniques give a clear idea about what kind of information you need for your project.

How to Gather Qualitative vs Quantitative Data
There are different ways to gather the data depending on the research method technique that will be used.
Gathering Qualitative Data:
- In-Depth Interviews: Ask open-ended questions from people to get to know their experiences and perspectives.
- Focus Groups: have discussions within a group to gather different insights.
- Observation: observe the behaviors and interactions in natural settings.
- Document Analysis: analyze reports and texts to draw insights from them.
Tips for qualitative collection:
- Be flexible and ready to follow interesting responses.
- Keep track of themes and patterns as they emerge.
- Tools like transcription software can help organize large amounts of narrative data.
Gathering Quantitative Data:
- Surveys/Questionnaires: Structured questions with multiple-choice or rating scales.
- Experiments: Manipulate variables in controlled settings.
- Secondary Data Analysis: Use existing databases for trends and patterns.
- Tests and Assessments: Measure performance and give the findings in percentages and numerical values.
If you want both numerical as well as opinion-based findings, you can choose a mixed-method approach for a complete picture. There are several students who even turn to online dissertation help so they can get help in conducting their research.

Practical Qualitative vs Quantitative Data Examples
Seeing examples makes the difference clearer:
Qualitative Examples:
- Use the Interview transcripts to explain user preferences.
- Doing classroom observations to highlight engagement.
- Taking customer feedback to describe their satisfaction or frustration.
- Taking Ethnographic notes to analyze cultural practices.
Quantitative Examples:
- Doing a survey to show the percentage of how many students who prefer online learning.
- Compare teaching methods and their effect on Test scores.
- Collecting the data on sales to record monthly revenue trends.
Benefits of Each Approach
There are different benefits for each approach, which are given below in a simple manner.
Qualitative Benefits:
- Depth and Context: It allows for in-depth analysis of motivations, emotions, and experiences.
- Flexibility: Methods can evolve as insights emerge.
- Hypothesis Generation: Explore unknown areas and form new ideas.
- Human-Centered Insights: Stories and quotes show real-world experiences.
Quantitative Benefits:
- Objectivity: Numbers reduce personal bias.
- Measurability: Track trends or patterns over time.
- Generalizability: Large samples support broader conclusions.
- Data-Driven Decisions: Informs evidence-based strategies efficiently.
Both of the approaches have their own benefits, but the decision to choose depends on your goals and resources.
Limitations to Keep in Mind
Every method has its limitations, and these should be kept in mind before choosing any method.
Qualitative Limitations:
- Needs more time and resources.
- Has a small sample, so findings can’t be generalized.
- There can be research bias in this.
Quantitative Limitations:
- Has the tendency to overlook the underlying motivations behind the numbers.
- Due to predefined questions, new insights can be missed.
- Need a large number of samples to be collected.
Understanding these limitations can help you to base your decision on your time and resources.
How to Analyze The Data
Analyzing data properly ensures your research leads to meaningful insights.
Analyzing Qualitative Data:
- Content Analysis: To do content analysis, group similar themes, concepts, or ideas from the data.
- Thematic Analysis: Create themes from the data to understand the participants’ responses.
- Discourse Analysis: To analyze the language and context to reveal cultural or social influences.
- Interpretation: Interpret the reason behind the behaviors and motivations.
Analyzing Quantitative Data:
- Descriptive Statistics: To analyze the numerical data through averages, percentages, or values.
- Inferential Statistics: To test the hypotheses and generalize the findings to broader populations.
- Visual Representation: Use Charts, tables, and graphs to show trends, patterns, and correlations.
- Statistical Software: Use software like SPSS, R, or Excel to analyze the data easily.
Conclusion
Qualitative and quantitative research methods are both used widely by researchers. But choosing the best method for your own dissertation and thesis depends on the research goals and the type of findings you need, such as opinion-based or numerical-based. Qualitative research explores experiences and motivations, while quantitative research measures and generalizes the patterns. There is another method, which is a mixed method that combines both of these approaches and gives a complete picture of the study from both angles. You need to keep your time limit and resources in mind when choosing any method.
