Study Notes

Quantitative Research Overview

An inquiry approach using numerical data to describe relationships and phenomena in nature.
Characteristics include controllability, generalizability, objectivity, and replicability.
Strengths lie in understanding the universe, though it needs complementary qualitative approaches for a full perspective.

Types of Quantitative Research

Descriptive Research: Focuses on accurately portraying characteristics of a population.
Comparative Research: Compares two or more groups or conditions.
Correlational Research: Examines relationships between variables; includes survey research for attitudes and trends.
True Experimental Research: Investigates cause-and-effect relationships; manipulates independent variables and measures dependent variables.
Quasi-Experimental Research: Similar to true experiments but lacks random assignment.

Research Tools

Surveys: Utilize questionnaires to collect numerical data from sampled populations.
Experimental Setup: Participants divided into experimental (receiving treatment) and control groups.

Variables in Research

Variables can be independent (manipulated), dependent (measured), mediating, moderating, or extraneous.
Levels of measurement include categorical (groups) and continuous (scale).
Understanding variable roles aids in data analysis and interpretation.

Research Writing Phases

Identifying areas of inquiry is crucial and involves specific steps to outline research purpose and scope.
The research title summarizes the study scope concisely and should be focused, formal, and grammatically correct.

Research Scope and Limitations

Scope outlines general study boundaries; limitations account for unforeseeable factors impacting results.
Delimitation specifies researcher-imposed boundaries for the study.

Research Problem and Questions

The statement of the problem adds context to the research; it is guided by research questions.
Types of research questions include descriptive, comparative, evaluative, and explanatory, and must be relevant and measurable.

Hypotheses in Research

A well-defined hypothesis is crucial and should be falsifiable, predictable, clear, and based on existing knowledge.
Types include null (no effect) and alternative (indicating effect), with subcategories of directional and nondirectional hypotheses.
Type I and Type II errors can arise from faulty aspects of the research.

Frameworks in Research

Conceptual frameworks integrate diverse ideas, guiding the research process.
Theoretical frameworks are based on existing theories relevant to the study.
Both frameworks emphasize main constructs and concepts within the research.

Definitions in Research

Conceptual Definition: Defines concepts theoretically.
Operational Definition: Specifies how concepts will be measured or identified in practice.
