Qualitative vs. Quantitative: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 8, 2024
Qualitative research focuses on understanding characteristics and descriptions, often through observation and interviews, while quantitative research involves numerical data and statistical analysis.

Key Differences

Qualitative research is exploratory, aiming to understand underlying reasons and motivations, in contrast to quantitative research, which seeks to quantify data and generalize results from sample to population.
In qualitative research, data collection includes interviews, focus groups, and observations, providing in-depth insights, whereas quantitative research uses structured tools like surveys and questionnaires for data collection.
Qualitative analysis is interpretive, focusing on themes and patterns in non-numerical data, while quantitative analysis relies on statistical methods and mathematical calculations.
The outcome of qualitative research is more descriptive, capturing the complexity of human behavior, in contrast to quantitative research that results in numerical outputs and generalizable findings.
In qualitative research, the researcher often has a closer, more subjective relationship with the data, unlike in quantitative research, where the researcher maintains distance and objectivity.

Qualitative and Quantitative Definitions


Qualitative research involves descriptive data analysis.
A qualitative study on culture may involve participant observation.


Quantitative data is statistically analyzed for patterns.
Quantitative researchers use statistical software for data analysis.


Qualitative data is typically text-based and detailed.
Qualitative interviews provide rich, detailed narratives.


Quantitative methods aim to quantify variables and generalize findings.
A quantitative study might involve a large-scale population survey.


In qualitative research, data collection is often unstructured.
Qualitative field research might involve open-ended questions.


Quantitative research involves numerical data collection and analysis.
A quantitative survey might measure consumer preferences with a rating scale.


Qualitative methods focus on understanding human behavior.
A qualitative researcher might study social interactions in a community.


Quantitative analysis produces numerical, generalizable results.
Quantitative studies often result in graphs and charts representing data.


Qualitative analysis seeks to interpret patterns and themes.
Qualitative coding involves identifying themes in interview transcripts.


In quantitative research, data collection is structured and standardized.
Quantitative data can include test scores or census data.


Of, relating to, or concerning quality.


Expressed or expressible as a quantity.


Of descriptions or distinctions based on some quality rather than on some quantity.


Of, relating to, or susceptible of measurement.


(chemistry) Of a form of analysis that yields the identity of a compound.


Of or relating to number or quantity.


Something qualitative.


Of or relating to a metrical system based on the duration of syllables rather than on stress. Used especially of classical Greek and Latin verse.


Relating to quality; having the character of quality.


Of a measurement based on some quantity or number rather than on some quality


Involving distinctions based on qualities;

What makes qualitative research unique?

Its emphasis on detailed, text-based data and subjective interpretation.

How is data analyzed in qualitative research?

Data is analyzed thematically and interpretively to identify patterns and insights.

What is qualitative research?

Qualitative research focuses on descriptive, non-numerical data to understand underlying reasons and motivations.

Can qualitative research provide statistical results?

No, qualitative research is descriptive and does not produce statistical outcomes.

What are examples of quantitative data?

Examples include survey results, test scores, and census data.

What are common qualitative research methods?

Common methods include interviews, focus groups, and participant observations.

Can quantitative research explain individual behaviors?

Quantitative research focuses more on general patterns than on in-depth individual behaviors.

What is quantitative research?

Quantitative research involves collecting and analyzing numerical data to identify statistical patterns.

Can qualitative research be used for policy making?

Yes, qualitative insights are valuable for understanding complex issues in policy making.

How is quantitative data analyzed?

It's analyzed using statistical methods to produce quantifiable results.

What is the goal of quantitative research?

To quantify variables and generalize results from samples to populations.

Which is better for understanding personal experiences, qualitative or quantitative?

Qualitative research is better suited for understanding detailed personal experiences.

Are mixed methods involving both qualitative and quantitative approaches common?

Yes, mixed methods combine the strengths of both approaches for comprehensive analysis.

Can quantitative data be converted into qualitative data?

Quantitative data can provide the basis for qualitative interpretation, but it remains fundamentally numerical.

How do qualitative and quantitative research differ in approach?

Qualitative research is exploratory and descriptive, while quantitative is conclusive and quantifiable.

What type of research is used for developing hypotheses?

Qualitative research is often used for hypothesis generation, while quantitative is used for testing them.

What skills are important for qualitative researchers?

Skills in observation, communication, and interpretative analysis are key for qualitative researchers.

How is reliability ensured in quantitative research?

Through standardized procedures and statistical validation methods.

What is a limitation of quantitative research?

It may not capture the complexity and depth of human experiences as qualitative research does.

How do sample sizes differ between qualitative and quantitative research?

Qualitative research often uses smaller, more focused samples, while quantitative research typically requires larger samples for statistical significance.
