Quantitative research is an
approach for testing objective
theories by examining the
relationship among variables.
Qualitative research is an
approach for exploring and
understanding the
meaning of individuals or
groups ascribe to a social
or human problem.
Mixed methods research is an approach
involving collecting both quantitative
and qualitative data, integrating the two
forms of data. 6
Types of Research Methodologies
Creswell, J. W. (2014). Research Design: Qualitative, Quantitative, and Mixed Methods Approaches (4th ed.)/ https://researcher.life/blog/article/choose-research-methodology

1. Quantitative Methods:
• Relies on numerical and statistical data to
quantify the problem.
• The primary aim is to identify general
patterns and predict future outcomes.
• This approach is rooted in the positivist
paradigm, where reality is assumed to be
stable, measurable, and observable.
Types of Research Methodologies
Creswell, J. W. (2014). Research Design: Qualitative, Quantitative, and Mixed Methods Approaches (4th ed.)./ https://researcher.life/blog/article/choose-research-methodology

• Quantitative research aims to produce
reliable, replicable, and valid results by
focusing on structured techniques and large
sample sizes.
• Quantitative research employs structured tools
like surveys, experiments, and numerical data
to test theories.
• The goal is often to establish relationships or
causality between variables.

2. Qualitative Methods:
• Involves non-numerical data to explore
concepts, experiences, or social
phenomena in depth.
• It seeks to understand how individuals
interpret or make sense of their world.
• In contrast, qualitative research is aligned
with the constructivist or interpretivist
paradigms.
Types of Research Methodologies
Merriam, S. B., & Tisdell, E. J. (2015). Qualitative Research: A Guide to Design and Implementation/ https://researcher.life/blog/article/choose-research-methodology

• The goal is to capture the subjective
experiences of participants, offering rich,
detailed narratives.
• This method is often used when the
researcher seeks to understand social
processes, behaviors, or cultural
phenomena.

3. Mixed Methods:
• Integrates both quantitative and qualitative
approaches, leveraging the strengths of both
to provide a richer, more nuanced
understanding.
• The mixed-method approach is pragmatic,
integrating quantitative and qualitative
techniques to capitalize on the strengths of
each.
Types of Research Methodologies
Creswell, J. W., & Plano Clark, V. L. (2017). Designing and Conducting Mixed Methods Research/ https://researcher.life/blog/article/choose-research-methodology
12
• By combining these methods, mixed
methods research can validate findings,
explore diverse perspectives, and uncover
deeper insights that might be missed when
using a single methodology.
• It is particularly useful in studies requiring
both broad statistical analysis and detailed,
context-rich exploration, making it a versatile
tool for addressing multifaceted issues in
various fields.
Examples for Context

1. Quantitative Study in Civil Engineering:
• A quantitative study in civil engineering could
explore the relationship between the frequency of
preventive maintenance and the structural
lifespan of bridges across a region using
regression analysis.
• For instance, data from 50 bridges could be
analyzed to quantify how maintenance intervals
influence material degradation rates, providing
actionable insights for infrastructure management.

3. Mixed-Method Study in Renewable Energy
Engineering:
• A mixed-method study in renewable energy
engineering might begin with quantitative surveys to
assess the efficiency of solar panel installations in urban
areas, followed by qualitative interviews with engineers
to explore challenges in panel design and placement.
• For example, survey data from 200 installations could
highlight performance trends, while interviews could
uncover design constraints such as shading or local
regulations that influence these trends.
Choosing the Right Research Methodology
Bryman, A. (2016). Social Research Methods/https://researcher.life/blog/article/what-is-quantitative-research-types-and-examples
16
▪ Why Choosing the Right Method Matters:
• The choice of research method determines how
effectively you can answer your research questions.
• For example, if you're exploring the lived experiences
of engineers working in high-stress environments,
such as those managing critical infrastructure during
natural disasters, qualitative methods will offer
insights into their subjective experiences, coping
mechanisms, and decision-making processes that
quantitative methods cannot capture.
Choosing the Right Research Methodology
Bryman, A. (2016). Social Research Methods/https://researcher.life/blog/article/what-is-quantitative-research-types-and-examples
17
• Selecting the appropriate research
methodology is crucial for ensuring that the
research question is addressed effectively and
rigorously.
• The choice should be based on several critical
factors, including the nature of the research
problem, the goals of the research, the type of
data required, and the philosophical orientation
of the researcher.

19
1. Nature of the Research Problem:
• Quantitative methods are often suitable for
research that seeks to test a theory or establish
cause-and-effect relationships.
• Qualitative methods are better for exploratory
research where the objective is to gain a deep
understanding of a phenomenon.
2. Research Objectives:
• Is the goal to measure and quantify variables or
to explore concepts and perspectives?
Factors Influencing Methodology Selection
Patton, M. Q. (2002). Qualitative Research & Evaluation Methods/ https://gencraft.com/generate
20
3. Research Questions:
• Quantitative research often involves questions
that begin with "how much," "what is the
correlation," or "to what extent."
• Qualitative research questions are open-ended
and exploratory, such as "how" and "why"
questions that seek to understand complex
human behaviors.
Factors Influencing Methodology Selection
Patton, M. Q. (2002). Qualitative Research & Evaluation Methods/ https://gencraft.com/generate

4. Practical Considerations:
• Available resources, including time, access to
participants, and funding, can impact the
choice of methodology.
• The familiarity and expertise of the
researcher with particular methods can also
influence the selection.
Positivism
Constructivism
Interpretivism
Pragmatism
Research Paradigms
Guba, E. G., & Lincoln, Y. S. (1994). Competing Paradigms in Qualitative Research
▪ A research paradigm represents a worldview that shapes how research is
designed, conducted, and interpreted. The four major paradigms are:
22
Types of Research Paradigms
Crotty, M. (1998). The Foundations of Social Research: Meaning and Perspective in the Research Process/ https://gencraft.com/generate
23
1. Positivism:
• Assumes that reality is objective and can be
discovered through empirical observation and
measurement.
• Positivism aligns with quantitative methods, as it
supports the idea that phenomena can be observed
and quantified in a controlled, objective manner.
• Research designs based on positivism often use
structured techniques, such as experiments and
surveys, to produce generalizable findings.
Types of Research Paradigms
Crotty, M. (1998). The Foundations of Social Research: Meaning and Perspective in the Research Process/ https://gencraft.com/generate
24
2. Interpretivism:
• Contrasts with positivism, as it holds that reality is
socially constructed and cannot be understood
through objective measurement alone.
• Interpretivism aligns with qualitative methods, as it
seeks to understand the subjective meanings that
people attach to their experiences.
• Interpretive research often involves close
interaction between the researcher and participants,
with an emphasis on context and depth.
Types of Research Paradigms
Crotty, M. (1998). The Foundations of Social Research: Meaning and Perspective in the Research Process/ https://gencraft.com/generate
25
3. Constructivism:
• Closely related to interpretivism but places more
emphasis on the co-construction of knowledge
between researchers and participants. Knowledge
is seen as evolving, not static.
• Methods include participant observation, interviews,
and document analysis, focusing on understanding
the processes by which individuals make sense of
their world.
Types of Research Paradigms
Crotty, M. (1998). The Foundations of Social Research: Meaning and Perspective in the Research Process/ https://gencraft.com/generate
26
4. Pragmatism:
• A flexible paradigm that focuses on the research
problem rather than the specific methods used.
• It advocates for using whichever methods—
quantitative, qualitative, or mixed—are best suited
to the research question.
• Pragmatism aligns well with mixed methods
research, as it focuses on the practical
implications and outcomes of research.

Research
Aim of Research
Stebbins, R. A. (2001). Exploratory Research in the Social Sciences
▪ The aim of research are typically framed by the type of question the researcher seeks
to answer. The research aim reflects the goals of the investigation and guides the
methodology, data collection, and analysis. Common research aims include:

27
Aim of Research
Stebbins, R. A. (2001). Exploratory Research in the Social Sciences / https://gencraft.com/generate
28
1. Exploratory Research:
• Conducted when the subject is new or not well
understood. The goal is to gain insights and
familiarity with a phenomenon, often using
qualitative methods like case studies or
interviews.
• Example: An exploratory study might
investigate the factors that influence social
media usage among teenagers, aiming to
uncover new themes or patterns.
Aim of Research
Stebbins, R. A. (2001). Exploratory Research in the Social Sciences / https://gencraft.com/generate
29
• Often conducted in areas where little prior
research exists, exploratory studies help
researchers formulate hypotheses or
understand the boundaries of a research
question.
• For example, in emerging fields like artificial
intelligence ethics, exploratory research might
involve interviews with experts to identify key
ethical concerns.
Aim of Research
Stebbins, R. A. (2001). Exploratory Research in the Social Sciences / https://gencraft.com/generate
30
2. Descriptive Research:
• Aims to describe the characteristics of a
population or phenomenon.
• This type of research often involves surveys or
observational studies to gather data on "what
is.”
• Example: A descriptive study might measure
the level of job satisfaction among nurses in a
particular hospital.
Aim of Research
Neuman, W. L. (2014). Social Research Methods: Qualitative and Quantitative Approaches / https://gencraft.com/generate
31
• Descriptive studies do not attempt to draw
causal connections but aim to provide a
detailed picture of a situation as it exists.
• An example could be a national survey on
health care access, where the goal is to
describe patterns across different
demographic groups.
Aim of Research
Neuman, W. L. (2014). Social Research Methods: Qualitative and Quantitative Approaches / https://gencraft.com/generate
32
3. Explanatory Research:
• Seeks to explain the relationships between
variables. This is typically the domain of
quantitative research, where hypotheses are
tested to determine cause-and-effect
relationships.
• Example: An explanatory study might
investigate the relationship between
socioeconomic status and academic
achievement using regression analysis.
Aim of Research
Neuman, W. L. (2014). Social Research Methods: Qualitative and Quantitative Approaches / https://gencraft.com/generate
33
• Explanatory research is designed to test
theories and often involves rigorous statistical
techniques to establish causality.
• For example, a study on the effects of
education policies might use a longitudinal
design to track changes in student performance
over time, testing for the influence of new
reforms.

Quantitative Research: A Scientific
Approach
The Evolution of Quantitative Research
Bryman, A. (2016). Social Research Methods / https://gencraft.com/generate
35
▪ Origins of Quantitative Research:
• Stemming from the natural sciences (e.g.,
physics, chemistry), it was initially developed to
study phenomena through empirical,
measurable evidence.
▪ Milestones:
• 17th Century: Early use of statistics in
population studies and economics.
• 19th Century: Introduction of randomized trials
and experimental methods in medical research.
The Evolution of Quantitative Research
Bryman, A. (2016). Social Research Methods / https://gencraft.com/generate
36
• 20th Century: Widespread use in the social
sciences to understand human behaviors,
trends, and economic patterns.
▪ Key Theories & Influences:
• Positivism: The belief that knowledge can only
be derived from logical and empirical
observation.
• Critical Rationalism (Karl Popper): Introduced
the concept of falsifiability in hypothesis testing.
Quantitative Research: A Scientific Approach
Bryman, A. (2016). Social Research Methods (5th ed.). Oxford University Press / https://gencraft.com/generate
37
▪ Definition:
• Quantitative research is structured and seeks to
quantify the relationships between variables.
• It’s typically used in studies where the goal is to test
hypotheses, predict outcomes, and find correlations.
▪ Key Characteristics:
1. Hypothesis-Driven: Researchers often begin with
a hypothesis based on existing theories or previous
studies. The goal is to confirm or refute this
hypothesis by collecting measurable data.
Quantitative Research: A Scientific Approach
Bryman, A. (2016). Social Research Methods (5th ed.). Oxford University Press / https://gencraft.com/generate
38
2. Measurable Variables: Variables are
operationalized to allow for clear, precise
measurement.
• For instance, rather than studying "happiness,"
researchers might measure happiness using a
standardized psychological scale (e.g., a 1–7
Likert scale).
Quantitative Research: A Scientific Approach
Bryman, A. (2016). Social Research Methods (5th ed.). Oxford University Press / https://gencraft.com/generate
39
3. Deductive Approach: Starts from a theory,
develops a hypothesis, collects data, and
then tests whether the data supports the
hypothesis.
4. Large Sample Sizes: The emphasis on
generalizability requires large sample sizes to
ensure findings are representative of a
broader population.

• While quantitative data provides a broad
overview (e.g., trends in a population), qualitative
data offers depth and context (e.g., personal
experiences of individuals within that population).
2. Triangulation:
• Mixed methods allow researchers to cross-
validate findings by comparing data from multiple
sources or methods.

Creswell, J. W., & Plano Clark, V. L. (Designing and Conducting Mixed Methods Research (3rd ed.)/https://www.dragnsurvey.com/blog/en/the-difference-between-survey
70
• For example, if qualitative interviews confirm
trends seen in survey data, this strengthens the
validity of the research.
3. Concurrent or Sequential:
• In concurrent designs, both types of data are
collected simultaneously, while in sequential
designs, one type of data informs the other.

71
The procedures of collecting, analysing and mixing the data are
based on three main characteristics according to Moris, 1991:
▪ Timing:
• The sequence or order of the implementation of the
qualitative and the quantitative data collection and
analysis procedures in the study (either Sequentially or
Concurrently).
▪ Weighting:
• The relative importance or priority given to each type of
data (to consider the priority or the emphasis).

72
▪ Mixing:
• How the two methods (quantitative & qualitative)
integrate within the study. Deciding on how to mix
the methods depends on the (purpose, design and
strategies) that are used for collecting and analysis.

▪ When do we conduct a Mixed Methods Study:
• When we have both quantitative and qualitative
data.
• When one data resource may not be enough to
explain the answer of the question.
• When we want qualitative research to help in
explaining the quantitative findings.
• Want to provide alternative perspectives in a study.
• When we want to generalize findings to a large
population.

▪ Reasons for using Mixed Methods Research:
• Combines the strengths of both quantitative and
qualitative approaches to provide a more holistic
view of the research problem.
• Enhances the validity and reliability of findings by
cross-verifying results from different methods.
• Allows researchers to explore a phenomenon
qualitatively and then confirm findings
quantitatively (or vice versa).

When to Use Which Methodology
Creswell, J. W. (2013). Qualitative Inquiry and Research Design: Choosing Among Five Approaches (3rd ed.)/https://www.qualitylogic.com/knowledge-center
89
▪ Choosing the Right Methodology
• Quantitative Research: Best suited when the goal is to
measure variables, predict outcomes, or establish causality.
• It's appropriate for research questions such as "What is the
effect of X on Y?" or "How much do variables A and B
correlate?”
• Example: A researcher studying the correlation between
social media use and anxiety might use a large-scale
survey to quantify the relationship between time spent
on social media and self-reported anxiety levels.
When to Use Which Methodology
Creswell, J. W. (2013). Qualitative Inquiry and Research Design: Choosing Among Five Approaches (3rd ed.)/ https://www.qualitylogic.com/knowledge-center
90
• Qualitative Research: Useful for exploratory
research that seeks to understand underlying
meanings or experiences.
• It's suitable for questions like "How do individuals
experience X?" or "What are the processes behind
Y?“
• Example: A study exploring the lived
experiences of refugees might use in-depth
interviews to understand their emotional and
psychological struggles.
When to Use Which Methodology
Creswell, J. W. (2013). Qualitative Inquiry and Research Design: Choosing Among Five Approaches (3rd ed.)/https://www.qualitylogic.com/knowledge-center
91
• Mixed Methods Research: Best when neither
quantitative nor qualitative methods alone are
sufficient to fully address the research problem.
• It's appropriate for research that requires both
breadth and depth.
• Example: A study examining student
performance might start by collecting test
scores (quantitative) and then conducting focus
groups to understand students' attitudes and
behaviors (qualitative).
Challenges and Criticisms
Johnson, R. B., & Onwuegbuzie, A. J. Mixed Methods Research: A Research Paradigm Whose Time Has Come https://researcher.life/blog/article/choose-research-methodology
92
▪ Quantitative Research Challenges:
• Ethical Concerns: Manipulating variables in
experimental settings can raise ethical issues.
• Over-Simplification of Complex Issues:
Quantitative methods might reduce complex social
phenomena to a few measurable variables,
potentially missing the broader context.
• External Validity: Generalizability is often a
challenge when the study sample doesn't
accurately reflect the target population.
Challenges and Criticisms
Johnson, R. B., & Onwuegbuzie, A. J. Mixed Methods Research: A Research Paradigm Whose Time Has Come https://researcher.life/blog/article/choose-research-methodology
93
▪ Qualitative Research Challenges:
• Researcher Bias: Since qualitative analysis often
involves interpretation, there's a risk of the
researcher's personal biases influencing the results.
• Reliability and Replicability: It's difficult to replicate
qualitative studies due to the context-specific nature of
the data.
• Time-Consuming: Collecting and analyzing qualitative
data can take much longer than quantitative methods,
especially for large datasets or ethnographic studies.
Challenges and Criticisms
Johnson, R. B., & Onwuegbuzie, A. J. Mixed Methods Research: A Research Paradigm Whose Time Has Come https://researcher.life/blog/article/choose-research-methodology

▪ Mixed Methods Research Challenges:
• Complexity of Design: Designing and implementing
mixed methods research requires careful planning and
expertise in both qualitative and quantitative approaches.
• Integration of Data: Combining qualitative and
quantitative data can be difficult, particularly when the
findings conflict.
• Resource Intensive: Mixed methods research requires
more time, money, and expertise than using a single
method.
Conclusion

• Quantitative, qualitative, and mixed methods research
each offer unique strengths and address different types
of research questions.
• Understanding the procedures of collecting and
analyzing the quantitative and qualitative data will
enable us to reach an effective research design using
mixed method research.
• By integrating these approaches, researchers can offer
more robust, well-rounded conclusions that account for
both measurable data and nuanced human experiences.

  • 28.
    Aim of Research Stebbins,R. A. (2001). Exploratory Research in the Social Sciences / https://gencraft.com/generate 28 1. Exploratory Research: • Conducted when the subject is new or not well understood. The goal is to gain insights and familiarity with a phenomenon, often using qualitative methods like case studies or interviews. • Example: An exploratory study might investigate the factors that influence social media usage among teenagers, aiming to uncover new themes or patterns.
  • 29.
    Aim of Research Stebbins,R. A. (2001). Exploratory Research in the Social Sciences / https://gencraft.com/generate 29 • Often conducted in areas where little prior research exists, exploratory studies help researchers formulate hypotheses or understand the boundaries of a research question. • For example, in emerging fields like artificial intelligence ethics, exploratory research might involve interviews with experts to identify key ethical concerns.
  • 30.
    Aim of Research Stebbins,R. A. (2001). Exploratory Research in the Social Sciences / https://gencraft.com/generate 30 2. Descriptive Research: • Aims to describe the characteristics of a population or phenomenon. • This type of research often involves surveys or observational studies to gather data on "what is.” • Example: A descriptive study might measure the level of job satisfaction among nurses in a particular hospital.
  • 31.
    Aim of Research Neuman,W. L. (2014). Social Research Methods: Qualitative and Quantitative Approaches / https://gencraft.com/generate 31 • Descriptive studies do not attempt to draw causal connections but aim to provide a detailed picture of a situation as it exists. • An example could be a national survey on health care access, where the goal is to describe patterns across different demographic groups.
