Research methodologies can roughly be categorized into three group: quantitative, qualitative, and mixed-methods.
- Qualitative Research : This methodology is based on obtaining deep, contextualized, non-numerical data. It can occur, for example, through open-ended questioning of research particiapnts in order to understand human behavior. It’s all about describing and analyzing subjective phenomena such as emotions or experiences.
- Quantitative Research: This methodology is rationally-based and relies heavily on numerical analysis of empirical data . With quantitative research, you aim for objectivity by creating hypotheses and testing them through experiments or surveys, which allow for statistical analyses.
- Mixed-Methods Research: Mixed-methods research combines both previous types into one project. We have more flexibility when designing our research study with mixed methods since we can use multiple approaches depending on our needs at each time. Using mixed methods can help us validate our results and offer greater predictability than just either type of methodology alone could provide.
Below are research methodologies that fit into each category.
Qualitative Research Methodologies
1. case study.
Conducts an in-depth examination of a specific case, individual, or event to understand a phenomenon.
Instead of examining a whole population for numerical trend data, case study researchers seek in-depth explanations of one event.
The benefit of case study research is its ability to elucidate overlooked details of interesting cases of a phenomenon (Busetto, Wick & Gumbinger, 2020). It offers deep insights for empathetic, reflective, and thoughtful understandings of that phenomenon.
However, case study findings aren’t transferrable to new contexts or for population-wide predictions. Instead, they inform practitioner understandings for nuanced, deep approaches to future instances (Liamputtong, 2020).
2. Grounded Theory
Grounded theory involves generating hypotheses and theories through the collection and interpretation of data (Faggiolani, n.d.). Its distinguishing features is that it doesn’t test a hypothesis generated prior to analysis, but rather generates a hypothesis or ‘theory’ that emerges from the data.
It also involves the application of inductive reasoning and is often contrasted with the hypothetico-deductive model of scientific research. This research methodology was developed by Barney Glaser and Anselm Strauss in the 1960s (Glaser & Strauss, 2009).
The basic difference between traditional scientific approaches to research and grounded theory is that the latter begins with a question, then collects data, and the theoretical framework is said to emerge later from this data.
By contrast, scientists usually begin with an existing theoretical framework , develop hypotheses, and only then start collecting data to verify or falsify the hypotheses.
3. Ethnography
In ethnographic research , the researcher immerses themselves within the group they are studying, often for long periods of time.
This type of research aims to understand the shared beliefs, practices, and values of a particular community by immersing the researcher within the cultural group.
Although ethnographic research cannot predict or identify trends in an entire population, it can create detailed explanations of cultural practices and comparisons between social and cultural groups.
When a person conducts an ethnographic study of themselves or their own culture, it can be considered autoethnography .
Its strength lies in producing comprehensive accounts of groups of people and their interactions.
Common methods researchers use during an ethnographic study include participant observation , thick description, unstructured interviews, and field notes vignettes. These methods can provide detailed and contextualized descriptions of their subjects.
Example Study
Liquidated: An Ethnography of Wall Street by Karen Ho involves an anthropologist who embeds herself with Wall Street firms to study the culture of Wall Street bankers and how this culture affects the broader economy and world.
4. Phenomenology
Phenomenology to understand and describe individuals’ lived experiences concerning a specific phenomenon.
As a research methodology typically used in the social sciences , phenomenology involves the study of social reality as a product of intersubjectivity (the intersection of people’s cognitive perspectives) (Zahavi & Overgaard, n.d.).
This philosophical approach was first developed by Edmund Husserl.
5. Narrative Research
Narrative research explores personal stories and experiences to understand their meanings and interpretations.
It is also known as narrative inquiry and narrative analysis(Riessman, 1993).
This approach to research uses qualitative material like journals, field notes, letters, interviews, texts, photos, etc., as its data.
It is aimed at understanding the way people create meaning through narratives (Clandinin & Connelly, 2004).
6. Discourse Analysis
A discourse analysis examines the structure, patterns, and functions of language in context to understand how the text produces social constructs.
This methodology is common in critical theory , poststructuralism , and postmodernism. Its aim is to understand how language constructs discourses (roughly interpreted as “ways of thinking and constructing knowledge”).
As a qualitative methodology , its focus is on developing themes through close textual analysis rather than using numerical methods. Common methods for extracting data include semiotics and linguistic analysis.
7. Action Research
Action research involves researchers working collaboratively with stakeholders to address problems, develop interventions, and evaluate effectiveness.
Action research is a methodology and philosophy of research that is common in the social sciences.
The term was first coined in 1944 by Kurt Lewin, a German-American psychologist who also introduced applied research and group communication (Altrichter & Gstettner, 1993).
Lewin originally defined action research as involving two primary processes: taking action and doing research (Lewin, 1946).
Action research involves planning, action, and information-seeking about the result of the action.
Since Lewin’s original formulation, many different theoretical approaches to action research have been developed. These include action science, participatory action research, cooperative inquiry, and living educational theory among others.
Using Digital Sandbox Gaming to Improve Creativity Within Boys’ Writing (Ellison & Drew, 2019) is a study conducted by a school teacher who used video games to help teach his students English. It involved action research, where he interviewed his students to see if the use of games as stimuli for storytelling helped draw them into the learning experience, and iterated on his teaching style based on their feedback (disclaimer: I am the second author of this study).

Quantitative Research Methodologies
8. experimental design.
As the name suggests, this type of research is based on testing hypotheses in experimental settings by manipulating variables and observing their effects on other variables.
The main benefit lies in its ability to manipulate specific variables to determine their effect on outcomes which is a great method for those looking for causational links in their research.
This is common, for example, in high-school science labs, where students are asked to introduce a variable into a setting in order to examine its effect.
9. Non-Experimental Design
Non-experimental design observes and measures associations between variables without manipulating them.
It can take, for example, the form of a ‘fly on the wall’ observation of a phenomenon, allowing researchers to examine authentic settings and changes that occur naturally in the environment.
10. Cross-Sectional Design
Cross-sectional design involves analyzing variables pertaining to a specific time period and at that exact moment.
This approach allows for an extensive examination and comparison of distinct and independent subjects, thereby offering advantages over qualitative methodologies such as case studies or surveys.
While cross-sectional design can be extremely useful in taking a ‘snapshot in time’, as a standalone method, it is not useful for examining changes in subjects after an intervention. The next methodology addresses this issue.
The prime example of this type of study is a census. A population census is mailed out to every house in the country, and each household must complete the census on the same evening. This allows the government to gather a snapshot of the nation’s demographics, beliefs, religion, and so on.
11. Longitudinal Design
Longitudinal research gathers data from the same subjects over an extended period to analyze changes and development.
In contrast to cross-sectional tactics, longitudinal designs examine variables more than once, over a pre-determined time span, allowing for multiple data points to be taken at different times.
A cross-sectional design is also useful for examining cohort effects , by comparing differences or changes in multiple different generations’ beliefs over time.
With multiple data points collected over extended periods ,it’s possible to examine continuous changes within things like population dynamics or consumer behavior. This makes detailed analysis of change possible.
12. Quasi-Experimental Design
Quasi-experimental design involves manipulating variables for analysis, but uses pre-existing groups of subjects rather than random groups.
Because the groups of research participants already exist, they cannot be randomly assigned to a cohort as with a true experimental design study. This makes inferring a causal relationship more difficult, but is nonetheless often more feasible in real-life settings.
Quasi-experimental designs are generally considered inferior to true experimental designs.
13. Correlational Research
Correlational research examines the relationships between two or more variables, determining the strength and direction of their association.
Similar to quasi-experimental methods, this type of research focuses on relationship differences between variables.
This approach provides a fast and easy way to make initial hypotheses based on either positive or negative correlation trends that can be observed within dataset.
Methods used for data analysis may include statistic correlations such as Pearson’s or Spearman’s.
Mixed-Methods Research Methodologies
14. sequential explanatory design (quan→qual).
This methodology involves conducting quantitative analysis first, then supplementing it with a qualitative study.
It begins by collecting quantitative data that is then analyzed to determine any significant patterns or trends.
Secondly, qualitative methods are employed. Their intent is to help interpret and expand the quantitative results.
This offers greater depth into understanding both large and smaller aspects of research questions being addressed.
The rationale behind this approach is to ensure that your data collection generates richer context for gaining insight into the particular issue across different levels, integrating in one study, qualitative exploration as well as statistical procedures.
15. Sequential Exploratory Design (QUAL→QUAN)
This methodology goes in the other direction, starting with qualitative analysis and ending with quantitative analysis.
It starts with qualitative research that delves deeps into complex areas and gathers rich information through interviewing or observing participants.
After this stage of exploration comes to an end, quantitative techniques are used to analyze the collected data through inferential statistics.
The idea is that a qualitative study can arm the researchers with a strong hypothesis testing framework, which they can then apply to a larger sample size using qualitative methods.
When I first took research classes, I had a lot of trouble distinguishing between methodologies and methods.
The key is to remember that the methodology sets the direction, while the methods are the specific tools to be used. A good analogy is transport: first you need to choose a mode (public transport, private transport, motorized transit, non-motorized transit), then you can choose a tool (bus, car, bike, on foot).
While research methodologies can be split into three types, each type has many different nuanced methodologies that can be chosen, before you then choose the methods – or tools – to use in the study. Each has its own strengths and weaknesses, so choose wisely!
