In this article, we are going to study quantitative, qualitative, and mixed research methods. We have provided all the key points with clear examples to make them easy to understand. Let’s get started..
1. What is Quantitative Research Method?
Quantitative research is an objective, highly structured approach that focuses on generating numerical data and hard facts. Instead of exploring personal feelings or stories, it uses statistical, mathematical, and computational techniques to test hypotheses, identify patterns, and examine cause-and-effect relationships between variables. It operates through deductive reasoning to answer questions like "how many," "how much," or "to what extent," and is typically used to establish broad, generalizable facts about a population.
The data is entirely numerical and can be precisely measured and expressed using graphs, percentages, and statistics. Information is typically gathered through structured surveys with multiple-choice or closed-ended questions, controlled experiments, and secondary numerical datasets. Also, it requires large, representative sample sizes (often hundreds or thousands of participants) to produce statistically significant and reliable results.

Example: Suppose a researcher wants to study the impact of remote learning. They survey 500 high school students regarding their daily screen time and collect their latest test scores. They then use statistical software to determine if there is a mathematical correlation between hours of screen time and exam results.
When looking at the example above, you can clearly understand that this research method depends on numerical data. It also uses statistical software to evaluate data. So, this is a prime example of how the quantitative research method is applied to achieve successful results.
1.1. What software is used to evaluate data in the quantitative research method?
There is a wide variety of software available for evaluating data in quantitative research, ranging from basic spreadsheet applications to advanced statistical programming languages.
• SPSS (Statistical Package for the Social Sciences) / IBM SPSS Statistics: One of the most widely used tools, particularly in the social sciences, business, and education. It is known for its user-friendly interface and ability to handle both basic descriptive and complex inferential statistics.
• SAS (Statistical Analysis System): A powerful enterprise suite trusted by organizations for advanced analytics, predictive modeling, and managing exceptionally large datasets.
• Stata: Popular in econometrics, sociology, and public health, it balances a user-friendly interface with powerful analytical and longitudinal data capabilities.
• MATLAB: Known for its strong capacity to efficiently manage and analyze massive volumes of data.
• AMOS (Analysis of Moment Structures): Excels in covariance-based SEM, confirmatory factor analysis, and testing complex theoretical relationships between variables.
• SmartPLS: Specializes in Partial Least Squares SEM (PLS-SEM), making it ideal for exploratory research, theory development, and predictive modeling with non-normally distributed data.
• Mplus: A highly flexible latent variable modeling program that handles cross-sectional, longitudinal, and multilevel data, as well as both continuous and categorical variables.
You can also use the following free and open-source software to analyze your quantitative data easily.
• GNU PSPP
• JASP
• Excel
• Jamovi
• SOFA Statistics
• SciLab
• MacAnova
• Dataplot
• Statcato
2. What is Qualitative Research Method?
Qualitative research is an exploratory, interpretive method that focuses on non-numerical data like words, feelings, experiences, and meanings. It aims to build theories, explain phenomena, and explore lived experiences directly from the participants' point of view, rather than testing predefined mathematical hypotheses. Information is typically gathered through highly interactive and flexible methods like in-depth interviews with open-ended questions, focus groups, document analysis, and real-world observations. It relies on small, purposeful sample sizes (often ranging from 5 to 50 people) to achieve deep understanding, rather than needing massive groups for broad statistical generalization.

Example: Suppose A researcher conducts in-depth interviews with a small group of teachers to explore their lived experiences of teaching remotely during the pandemic. Through thematic analysis of their stories, the researcher identifies the complex emotional challenges they faced and the unique strategies they developed to cope.
2.1. How do we analyze data in qualitative research?
Data analysis in qualitative research involves evaluating non-numerical data—such as text, audio, and video—to identify underlying meanings, recurring patterns, and overarching themes. Because qualitative research relies on an inductive approach, the goal is to summarize, categorize, and interpret the data to build understanding or theories rather than to test mathematical hypotheses. However, Depending on the research goal, researchers might apply specific analytical frameworks.
2.1.1. Thematic Analysis
Focuses purely on identifying, analyzing, and reporting patterns (themes) within the data. It is a highly structured process of generating initial codes, searching for themes, and then defining and naming those themes.
2.1.2. Content Analysis
Systematically categorizes textual or visual data. This can be done inductively (letting the themes naturally emerge from the data) or deductively (using predefined categories to guide the analysis).
2.1.3. Grounded Theory
A method used to develop an entirely new theory based on the gathered data. It uses constant comparative methods and specific coding stages (open, axial, and selective coding) to build theoretical frameworks.
2.3. What software is used to evaluate data in the qualitative research method?
While qualitative data can be analyzed manually, many researchers use Computer-Assisted Qualitative Data Analysis (CAQDAS) tools to help them meticulously organize, code, and visualize large amounts of textual or audio data.
NVivo and ATLAS.ti are highly popular choices that support the analysis of text, audio, and video, offering visualization tools like word trees and mind maps.Also we can use AXQDA, Dedoose, HyperRESEARCH, WordStat, Open Code, and QDA Miner to analyze qualitative data. However lot of researches are use manual method to analize data.
3. Mixed Research Method
The mixed method (often called mixed-methods research) is an approach that combines both quantitative (numerical, structured, and statistical) and qualitative (textual, unstructured, and exploratory) data collection and analysis techniques within a single study. This approach is heavily tied to the philosophy of pragmatism. Pragmatic researchers focus on what works best to answer the specific research question, blending both objective (numbers) and subjective (personal experiences) viewpoints to find practical solutions. Also, By using multiple methods, researchers can cross-validate their findings. If your numerical survey data and your qualitative interview stories both point to the exact same conclusion, your research becomes much more robust and credible.
Example: Suppose a researcher wants to understand employee morale. They start by distributing a quantitative survey to 300 employees to assess job satisfaction on a numerical scale. Once they identify broad trends, they conduct qualitative in-depth interviews with 20 employees to explore the nuances of their experiences and exactly why they feel satisfied or burnt out.
Conclusion
In summary, qualitative and quantitative research methods are very important to successfully completing a research project. If you want to analyze numerical data, you can use the quantitative method. On the other hand, if you want to analyze non-numerical data, such as behavioral traits like kindness or bad behavior in children, you can use the qualitative research method. However, if you want to analyze both, you can easily use a mixed-methods approach for your research. That concludes this article.
