Nature of Inquiry and Research
Inquiry and research involve systematic processes aimed at discovering, understanding, and analyzing
information to answer questions or solve problems. Quantitative research, a key methodology, focuses
on numerical data and statistical analysis.
1. Characteristics, Strengths, Weaknesses, and Kinds of Quantitative Research
Characteristics
Relies on numerical data and measurable variables.
Uses structured tools like surveys, experiments, and tests.
Employs statistical techniques for analysis.
Results are objective and can be generalized if the sample is representative.
Hypotheses are tested systematically.
Strengths
Objectivity: Results are not influenced by personal biases.
Replicability: Methods can be repeated for verification.
Generalizability: Findings apply to larger populations when sampling is proper.
Precision: Clear numerical evidence supports conclusions.
Weaknesses
Limited Depth: Cannot fully explore emotions or reasons behind behaviors.
Context Insensitivity: May overlook cultural or situational nuances.
Fixed Approach: Predefined tools may restrict flexibility during the study.
Kinds of Quantitative Research
1. Descriptive Research: Describes characteristics of a population or phenomenon (e.g., census
data).
2. Correlational Research: Examines relationships between variables without causal inference
(e.g., relationship between hours studied and test scores).
3. Experimental Research: Tests causation by manipulating variables (e.g., impact of a new drug).
4. Quasi-Experimental Research: Similar to experiments but lacks random assignment (e.g.,
comparing two teaching methods).
5. Ex Post Facto Research: Investigates pre-existing conditions or effects (e.g., effects of smoking
on health).
