Study Notes

Defining the Framework and Developing Conceptual Definitions

Quantitative research: A conceptual framework provides broader significance and utility to research findings. Even without a theoretical basis, researchers must have conceptual rationale and clarity regarding the concepts under investigation.
Theory: An interrelated set of constructs, definitions, and propositions that systematically represent phenomena. It explains and predicts phenomena by specifying relationships between variables.
Characteristics of a Theory:
- Composed of concepts
- Consists of propositions that define relationships between concepts
- Created or invented, not merely discovered
- Not proven true
- It is used in quantitative research via deductive reasoning to make predictions about how phenomena would behave in a real world.
- In Qualitative research, theory is often the product of the research. Researchers inductively develop a theory rooted in the participants' experiences.
Concepts: Abstractions that categorize observations based on commonalities and differences. They are the building blocks of theories and vary in their level of abstraction.
Construct: A complex abstraction that is often deliberately invented or constructed.
Framework: The overall underpinnings of a study.
- Theoretical framework: Derived from one or more theories or paradigms, providing a broad, general explanation of relationships between concepts in a research study. It allows empirical testing and provides a rationale for the study.
- Conceptual framework: Utilizes specific and well-defined concepts and constructs to describe ideas about individuals, groups, situations, and events of interest to a discipline. It serves as a springboard for formulating research hypotheses and constructing more formal theories.
Difference between Theoretical and Conceptual Framework: While both frameworks contribute to organizing and explaining phenomena, they differ in their level of formality and scope. Theoretical frameworks rely on established theories, while conceptual frameworks offer a less formal, discipline-specific approach.
Remember to use a theory from your respective profession/discipline to explain and support your hypothesis.
- Examples of Theories:
  - Florence Nightingale's "Environmental Theory"
  - Hildegard Peplau "Theory of Interpersonal Relations"
  - Virginia Anderson "Nursing Need Theory"
  - Ida Jean Orlando, "Dynamic Nurse-Patient Relationship"
  - Plato's Problem
  - Cartesian Linguistics, by Descartes
  - Locke's Tabula Rasa
  - Skinner's Theory of Behaviorism
Conceptual Paradigm: A diagrammatic representation of a conceptual framework. It provides a specific visual representation of the study's flow and how the treatment or independent variable will influence the dependent variable.

Formulating the Hypothesis

Hypotheses: Statements that express researchers' expectations about relationships among study variables. They are predictions of expected outcomes.
Research Question vs. Hypothesis: A research question identifies the concepts under investigation and asks how they might be related, while a hypothesis proposes a predicted answer to that question.
Testing Hypotheses: Most quantitative studies are designed to test hypotheses through statistical analysis.
Acceptance/Rejection: Hypotheses are never proved or disproved, they are accepted or rejected, supported or not supported by the data.
Developing Hypotheses:
- Inductive hypotheses: Generalizations inferred from observed relationships. Observations lead to broader generalizations.
- Deductive hypotheses: Use theories as a starting point. Researchers deduce expected outcomes based on the truth of a general theory.
Types of Hypothesis:
- Simple Hypothesis: States an expected relationship between one dependent and independent variable.
State the Hypothesis:
- Identify the independent and dependent variables from the title and research problem.
- Determine whether the research problem or research questions will form the basis for your hypothesis.
- Word your hypothesis clearly and concisely in the present tense. The relationship can be stated in a positive or alternative way.
- A good hypothesis must be worded precisely, concisely, and in the active tense.
- The relationship may be stated in a positive way or alternative hypothesis.
