Study Notes
Overview of Research
- Definition: Research involves studying to gain facts and understanding about various subjects, starting from infancy through sensory experiences.
-
Types of Research:
- Basic Research: Aimed at generating new knowledge without immediate application.
- Applied Research: Focuses on practical applications of existing knowledge.
- Evolution of Knowledge: The need for constant updates in knowledge is crucial; research helps identify areas needing further inquiry.
- Motives for Research: Varied motivations include profit, humanitarian reasons, or historically, world domination (e.g., Nazi scientists under Hitler).
-
Goals of Research:
- Produce new knowledge.
- Implement new findings to foster further knowledge.
- Validate or challenge existing information.
- Encourage personal and professional development of the researcher.
Research Designs
-
Research Approaches:
- Quantitative: Examines relationships between variables using statistical methods.
- Qualitative: Explores phenomena and seeks explanations through narratives and observations.
-
Research Designs Overview:
- Correlational: Assesses the degree of relationship between variables statistically.
- Experimental: Investigates cause-and-effect relationships among variables, often through controlled conditions.
- Descriptive: Provides an overview of the current status of a variable without experimentation.
Variables in Quantitative Research
-
Types of Variables:
- Independent Variable: The manipulated variable to determine its effect on the dependent variable.
- Dependent Variable: The outcome variable affected by changes in the independent variable.
-
Measurement of Variables:
- All variables in research can be classified into measurable traits, essential for data collection and analysis.
-
Categorization of Variables:
- Categorical Variables: Divided into nominal (non-ranked, e.g., gender) and ordinal (ranked, e.g., social status).
- Numerical Variables: Split into interval (ranked with range, e.g., age) and ratio (absolute zero point, e.g., income).
Types of Categorical and Numerical Variables
- Nominal Variables: Classify individuals based on shared characteristics without a ranking system (e.g., religion, gender).
- Ordinal Variables: Classify and rank characteristics (e.g., class standings).
- Interval Variables: Numeric variables with ordered values lacking a true zero (e.g., temperature).
- Ratio Variables: Numeric variables with a true zero point, allowing meaningful comparisons (e.g., income, student count).
