I am going to explain the blog post “What is the difference between qualitative and quantitative?“
In the field of research, two distinct methodologies are often used to gather and analyze data: qualitative and quantitative research. These two approaches differ in their methods, data collection techniques, and the types of data they produce. However, the distinction between the two can be confusing for those new to the field. In this blog post, we will explore the key differences between qualitative and quantitative research.

10 Differences between qualitative and quantitative
Here is a list of 10 differences between qualitative and quantitative:
- Research question
- Data type
- Data collection
- Sample size
- Data analysis
Detail of 10 Differences between qualitative and quantitative
- Research question: Qualitative research is often used to explore complex phenomena and generate in-depth understanding of social and cultural contexts, while quantitative research is used to test hypotheses and establish cause-and-effect relationships.
- Data type: Qualitative research collects non-numerical data such as narratives, texts, and images, while quantitative research collects numerical data such as statistics and numerical measurements.
- Data collection: Qualitative research uses methods such as interviews, observations, and focus groups to collect data, while quantitative research uses methods such as surveys, experiments, and structured observations.
- Sample size: Qualitative research typically has a smaller sample size, as it emphasizes in-depth exploration of a few cases or participants. In contrast, quantitative research requires a larger sample size to achieve statistical power.
- Data analysis: Qualitative research uses techniques such as coding, categorization, and thematic analysis to analyze data, while quantitative research uses statistical methods such as regression analysis, ANOVA, and correlation analysis.
- Validity: Qualitative research emphasizes the validity of the interpretation of data, while quantitative research emphasizes the validity of the measurement of data.
- Objectivity: Qualitative research emphasizes the role of the researcher’s subjectivity in data interpretation, while quantitative research emphasizes objectivity and aims to minimize the researcher’s influence on the data.
- Generalization: Qualitative research does not aim to generalize findings to the larger population but rather to understand specific phenomena in-depth. Quantitative research aims to generalize findings to the larger population through statistical methods.
- Scope: Qualitative research is often focused on exploring complex phenomena in-depth, while quantitative research is often focused on establishing cause-and-effect relationships and testing hypotheses.
- Purpose: Qualitative research is often used to generate new theories and concepts, while quantitative research is often used to test and confirm existing theories.
In conclusion, qualitative and quantitative research differ in their research questions, data types, data collection techniques, sample sizes, data analysis, validity, objectivity, generalizability, scope, and purpose. It is important for researchers to carefully consider the strengths and limitations of each approach and choose the most appropriate method based on their research question and objectives.
