Study Notes
Research Design and Methodology
- Research design and methodology are explained within the domains of IT.
Typical Research Question
- Research questions often seek to answer "how many," "how frequently," "what percentage," "what proportion," or "to what extent" something happens.
- The typical outcome involves a set of numerical values suitable for statistical analysis, leading to inferences and comparisons.
Example
- In computer science, researchers might test the effectiveness of a new algorithm.
- Researchers might observe algorithm performance empirically in controlled or real-world environments.
- Objective measurements of efficiency, speed, and accuracy are compared to existing algorithms.
- Results are valid regardless of researcher expectations.
- Scientific theories and concepts guide the interpretation of results.
- The experiment should be replicable for validation.
- Research should be quantifiable, observable, and verifiable.
Methodologies
- Methodologies encompass a range of tools and techniques for understanding social reality and organizational function.
- Researchers interpret social aspects by reviewing documents like policies and meeting minutes.
- Interviews gather data from individuals familiar with the phenomenon being studied.
- Constructivist research heavily relies on participant accounts of lived experiences for analysis and conclusions.
Typical Interpretive Research Question
- Interpretivist research focuses on qualitative thinking, aiming to discover, generate, explore, identify, or describe events.
- Qualitative research questions often start with words like "how," "why," "in which ways," or "to what extent."
Example (Interpretivism)
- Interpretivism could be applied to understanding how people interact with technology or how organizational culture impacts IT system adoption.
- Qualitative data (through interviews or focus groups) is gathered and analyzed.
- Researchers examine the social and cultural contexts impacting user interaction with IT systems to interpret the collected data.
- Researchers construct meaning from the data regarding the usability and function of IT systems.
Pragmatism
- Pragmatism in research focuses on problem-solving and understanding specific problems.
- Researchers aren't restricted to a single methodology.
- Methods can be chosen from both the quantitative and qualitative realms to achieve a solution to a problem.
Typical Pragmatic Research Question
- Pragmatic research is focused on results and finding practical solutions, aiming to find solutions to specific problems.
- Examples include questions like: "How can adult literacy be increased?" or "How can software developer satisfaction be improved?"
Example (Pragmatism)
- A study improving user experience on a social media platform could use a pragmatic approach.
- Start by identifying a problem (e.g., declining user engagement).
- A quantitative survey could collect initial data on user behavior.
- Qualitative methods (like interviews or focus groups) provide deeper understanding of why the problem exists.
- Iterative development allows for prototyping, testing, and feedback rounds.
- Ultimately, the goal is to find a solution to improve the platform.
Realism
- Realism focuses on understanding the true nature of phenomena related to the research problem.
- Realists believe that both quantitative and qualitative data methods might not be fully adequate to understand a problem.
- They often employ constructivist case study methods to achieve a deep understanding.
- Realists aim to uncover truth by studying the properties and processes of things as they exist in reality.
Sample Critical Research Questions (Realism)
- Questions about Facebook content ownership and data disclosure.
- Issues surrounding the effectiveness of the "One Laptop Per Child" initiative.
- Whether Massive Open Online Courses (MOOCs) are truly free, and the limitations of online education.
Example (Realism)
- A realist researcher studying the performance of an AI algorithm might measure performance in real-world settings, observing how the algorithm interacts with real-world systems.
- In-depth case studies could examine how the AI algorithm functions in various real-world applications involving customer interactions.
- The methodology would investigate the algorithm's performance not confined to ideal laboratory settings.
Methodology
- Methodology fundamentally deals with the nature and framework of the research process, detailing the application of principles, methods, and techniques within a specific research field.
- Steps include identifying, selecting, collecting, processing, analyzing data, and drawing conclusions.
Consideration in Method Selection
- Researchers must consider the research problem's nature while selecting methodology to ensure data collection and analysis methods are suitable.
- They should decide on quantitative, qualitative, or mixed-methods approaches.
Research Design
- Research design provides a structured plan for generating knowledge.
- This involves defining the research problem, establishing hypotheses, and creating an analytical framework.
- Appropriate methods are selected for data collection, reporting, and analysis.
- This design encompasses action plans for qualitative, quantitative, or mixed-methods approaches.

IT Methodology Thinking Framework
- Summarizes relationships between philosophical assumptions, methodologies, research designs, and methods.
The Goal
- The research design should obtain valid results, whether objective or subjective/interpretive, to answer research questions accurately and meaningfully.
- Sound results can be achieved with meticulous, appropriate methodology.
- Steps used to clarify the methodology in a research paper are provided.
Steps for Research Design
- Identifying the research problem, defining the research philosophy, specifying suitable methodology, clarifying research methods, and evaluating the design methodology.
Types of Research Design
- The main designs include: descriptive, experimental, comparative, causal-comparative/quasi-experimental, and correlational research.
Descriptive Research Design
- This design aims to describe the general nature and characteristics of a phenomenon or event.
- Gathering information details the phenomenon's status and relevant circumstances.
- It's often a preliminary step in further, more comprehensive research.
- It frequently involves observing and gathering information regarding the phenomenon under study.
- It is often used to identify important variables for testing hypotheses.
Experimental Design
- Experimental design controls variables to identify cause-and-effect relationships.
- This involves employing statistical methods.
- This is ideal for assessing whether independent variables affect dependent variables.
- Experiments can take place outside of a laboratory setting.
- Real-world experiments often require controlled, randomized, and manipulated measurements for ensuring their accuracy and reliability.
Examples of Experimental Studies
- Some specific examples include evaluating AI tools in software development, investigating the impacts of malware attacks, or studying the use of AI in customer support.
Experimental Design Advantages
- It helps researchers limit the study scope using independent variables.
- The researcher has complete control over independent variables to examine cause and effect.
- Dependent variables are determined by the independent variables.
- The researcher differentiates dummy effects from actual effects.
- Enables researchers to determine what has happened (deductive) or will likely happen (predictive).
Comparative Study Design
- This involves comparing two or more things to determine which is better.
- Simple applications can compare two solutions, while broader applications can compare software development models or antivirus software.
Causal-Comparative/Quasi-Experimental Design
- Aims to identify causal relationships between variables.
- Participants are often assigned to groups without random assignment.
- It’s ideal for certain research situations like a real-world banking cybersecurity study where random assignment could be unethical or impossible to practically carry out.
Correlational Research Design
- This focuses on uncovering the relationship between two or more variable factors using statistical data.
- It aims to identify trends, patterns, and relationships within the data.
- Variables are not controlled by the researcher in this design; instead, they are investigated in their natural state.
- This design assesses the relationship among variables through statistical calculation of the correlation coefficient.
Research Methodology
- A systematic approach to finding explanations for a phenomenon, dealing with the overall research strategy.
- Specific approaches, procedures, or techniques for identifying, selecting, processing, and analyzing data are also highlighted.
- Methodology in research profoundly impacts research validity and reliability.
Three Main Methodological Issues
- Methodology encompassing how data is collected or generated, analyzed, and conclusions are drawn.
Three Main Methodologies
- Quantitative, qualitative, and mixed methods are the fundamental approaches to research.
- These methods encompass a variety of specific techniques and approaches.
Quantitative Methodology
- Emphasis on objective measurements and numerical data analysis.
- This approach typically utilizes questionnaires, surveys, or documentation for data collection.
- The approach ensures repeatability, transparency, and credibility in research.
- Structured interviews within this methodology focus on measurable questions or parameters, not motivations or open-ended expressions.
Quantitative Methodology (Continued)
- Hypothesis testing uses mathematical, computational, and statistical measures to support quantifiable inferences.
- Statistical analysis involves numeric data interpretation like ratios, percentages, and graphs for presenting results.
- Data is typically numerical and suitable for analysis through methods like gap analysis, trend analysis, statistical analysis, and SWOT analysis.
Qualitative Approach
- Focusing on non-numerical data, it seeks insights into individual perceptions.
- Narrative data (stories or accounts) and inductive reasoning (inferring patterns from observations) are key parts of a qualitative approach to data analysis and interpretation.
- The aim is to understand how people experience the elements of a phenomenon under study by focusing on individual perceptions, experiences, or words.
- It often uses techniques like interviews, observation, or documentary review.
Qualitative Data Collection Methods
- Qualitative data often utilizes methods like document analysis, interviews, observations, interviews, focus groups, or visuals (like pictures or videos).
- Semi-structured interviews, where researchers ask open-ended questions, are common in this approach to allow individuals to freely express their opinions.
Stages of Coding
- The analysis process may involve open coding (to establish initial categories), axial coding (analyzing relationships between codes), and selective coding (grouping codes into broader themes).
Data Analysis (Qualitative)
- Qualitative analysis involves using techniques to build interpretations from qualitative data.
Mixed-Methods Approach
- This combines both quantitative and qualitative methods in a single study.
- Needed when separate approaches aren't sufficient.
- The aim is to strengthen results via triangulation for a more complete picture of the issues.
Benefits of Mixed-Methods
- Expanding upon previous research.
- Providing richer, more reliable insights.
