Study Notes

Nature of Inquiry and Research

Inquiry: Synonymous with "investigation"; involves questioning to explore a subject.
Research Design Types: Two main categories are experimental and non-experimental research.
Quantitative Research: Focuses on numerical data collection and analysis, emphasizing statistics.
Experimental Design: Provides control over variables to establish cause-and-effect relationships.
Non-Experimental Design: Often equated with survey research; common in social sciences.

Characteristics of Quantitative Research

Hypothesis Testing: Primarily a confirmatory method aimed at testing and validating hypotheses.
Numerical Data: Involves metrics and symbols to quantify observations and relationships.

Strengths and Weaknesses of Quantitative Research

Strengths:
- Facilitates hypothesis development or testing.
- Results generally more reliable with larger populations.
- Indicates objective findings, minimizing biases.
Weaknesses:
- Can be time-consuming and costly.
- Requires extensive statistical analysis.
- May leave uncertainty in outcomes.

Kinds of Quantitative Research

Experimental Research: Involves controlled experiments with randomization.
- Types:
  - Pre-experimental: Observes a single group receiving intervention.
  - True experimental: Subjects are randomly assigned to groups.
  - Quasi-experimental: Utilizes existing groups without random assignment.
Descriptive or Observational Studies: Researchers observe and categorize behaviors without intervention.
Correlational Research: Investigates relationships between variables using:
- Bivariate studies: Correlation between two variables.
- Prediction studies: One variable predicts another.
- Multiple regression: Combines variables for comprehensive predictions.

Importance of Quantitative Research

Reliability and Objectivity: Offers valid, generalizable findings through statistical analysis.
Theory Testing: Confirms or refutes existing theories or hypotheses.
Complex Problem Simplification: Breaks down intricate issues into measurable components.

Variables in Quantitative Research

Definition: Variables are measurable characteristics or quantities, such as age, income, and eye color.
Types of Variables:
- Continuous: Measurable on a scale (e.g., height, weight).
- Attribute: Characteristics like intelligence or anxiety.
- Dichotomous: Takes on two values (e.g., yes/no).
- Latent: Traits not directly observable, such as personality.

Parts of Research

Introduction: Sets the stage for the research topic.
Statement of the Problem: Defines the research problem and objectives.
Background of the Study: Offers context, rationale, and research questions.
Theoretical Framework: Discusses foundational theories guiding the study.
Conceptual Framework: Maps relationships between variables and objectives.

Hypothesis

Research Hypothesis: A formal statement predicting the study's anticipated outcomes; serves as the basis for statistical testing.
