Study Notes

Definition of Quantitative Research

Quantitative research explains phenomena by collecting and analyzing numerical data using statistical methods.
It is suited for studying measurable phenomena like sales increases, turnover rates, or changes in student performance.
Researchers apply numeric values to relevant factors and variables to quantify results.
Employs mathematical formulas primarily from descriptive and inferential statistics.
Follows a systematic approach with logical steps and a pre-defined action plan.
Relies on deductive reasoning to generate and test predictions in real-world scenarios.

Characteristics of Quantitative Research

Reliable and objective results, minimizing researcher bias.
Utilizes statistics to generalize findings across a larger population.
Simplifies complex problems into a few variables for analysis.
Explores connections between variables to establish cause-and-effect relationships.
Tests theories or hypotheses based on sampled, representative populations.
Subjectivity is secondary; focus is primarily on measurable details.

Advantages of Quantitative Research

Facilitates precise measurement and analysis, leading to clear answers.
High reliability due to large sample sizes enhancing validity.
Established standards for sampling and statistical treatment promote replicability.
Reduces personal bias by minimizing researcher-participant interaction.
Systematic processes simplify the research approach.
Results summarized easily through statistical methods.

Disadvantages of Quantitative Research

Ignores contextual details, focusing heavily on numerical data.
Requires substantial resources for large sample studies.
Results may lack depth, relying heavily on numerical analysis rather than narrative insights.
Less comprehensive regarding human perspectives and experiences.
Laboratory-controlled environments may not reflect real-world scenarios.
Fixed answer options may fail to capture true participant sentiments.
Researcher bias can occur due to participant unfamiliarity.

Importance of Quantitative Research in Various Fields

Valuable in academic settings for measuring performance and assessing methods.
Useful for analyzing stakeholder satisfaction in education, including parents and community.
Functions in various disciplines, including health, social sciences, and market research, to validate findings through quantifiable metrics.

Types of Variables

Continuous Variables: Can assume any value within a range (e.g., height, weight).
Discrete Variables: Limited to whole numbers (e.g., number of children).
Categorical Variables: Descriptive values failing to follow a logical order.
Ordinal Variables: Can be ranked (e.g., academic grades).
Nominal Variables: Categories without a sequence (e.g., colors).
Dichotomous and Polychotomous Variables: Represent two or multiple categories, respectively.
Experimental Variables: Include independent (manipulated), dependent (affected by manipulation), and extraneous variables.
Non-experimental Variables: Predictor variables (influence others) and criterion variables (influenced by predictors).
Univariate, Bivariate, and Polyvariate Studies: Focus on one, two, or more variables respectively.

Guidelines for Research Title Formulation

Should summarize the main idea and include major variables.
Reflect the relationship between said variables and the researcher's tasks.
Generalize participant descriptions for clarity.
Avoid redundant or misleading words; maintain brevity (10-15 words).

Identifying Research Problems

Can arise from discomforts, gaps in practice, or observable patterns needing investigation.
Sources include literature reviews, personal experiences, and trends identified in communities or specific settings.
Factors influencing problem selection include researcher motivations, resource availability, time management, and potential challenges.
Methodology for selecting a specific research title involves initial topic broadening, aspect narrowing, and formulation of focused variants.

Research Process Considerations

Initial topics should focus on specific issues or concerns.
Refinement through clustering or mapping ideas enhances focus.
Final formulation leads to a narrowed research problem, guiding title creation.
