Nature of Quantitative Research

Nature of Quantitative Research

Characteristics of Quantitative Research

• Reliable and objective methodology for research.
• Utilizes statistics for generalizing findings across a larger population.
• Simplifies complex problems to a manageable number of variables.
• Investigates relationships between variables to establish cause and effect, often in controlled environments.
• Tests theories or hypotheses through systematic approaches.
• Assumes representativeness of the sample relative to the population.
• Subjectivity in methodology is less of a concern compared to other research types.
• Focuses on the details of the subject rather than broader context.

Disadvantages of Quantitative Research

• Contextual factors may be overlooked, lacking consideration for the natural settings of studies.
• Larger sample sizes can increase resource and time demands on researchers.
• Results often rely on numerical analysis, potentially neglecting rich qualitative insights.
• Provides limited narratives on human perceptions and experiences.
• Rigor in experimental control may not accurately reflect real-world circumstances.
• Fixed alternatives may not capture the true feelings or responses of participants.
• Findings may be influenced by the researcher’s perspective, especially with unknown participants.

Advantages of Quantitative Research

• Enables measurement and detailed analysis for objective answers to research questions.
• Generally yields reliable results due to large sample sizes.
• Employs established standards for instrument selection, sampling, and statistical treatment, promoting replicability.
• Reduces personal biases by minimizing direct interaction between researcher and subjects.
• Streamlines processes, making quantitative research systematic and straightforward.
• Interpretable findings through statistical analysis facilitate concise conclusion and reporting.

Importance of Quantitative Research in Different Fields

• Education: Measures performance levels of students and teachers; assesses method and program effectiveness.
• Business: Enhances marketing strategies; informs company decisions regarding products and services.
• Medical and Health Care: Provides statistics on patient recovery rates; evaluates the efficacy of treatments and vaccines.
• Sciences: Promotes accountability and responsible operations in technological experiments.

Classifications of Variables

Types of Numeric Variables

• Continuous Variables: Can take any value within a given range; examples include time, height, and weight.
• Discrete Variables: Only assume whole values; examples include counts such as the number of cars or students.

Categorical Variables

• Ordinal Variables: Can be ranked; examples include academic grades and clothing sizes.
• Nominal Variables: Cannot be logically ordered; examples include types of businesses and hair colors.
• Dichotomous Variables: Represent two distinct categories; examples include gender (male/female).
• Polychotomous Variables: Have multiple categories; examples include levels of education or performance ratings.

Experimental Variables

• Independent Variables: Manipulated variables within an experiment to assess their effect on other variables.

The Research Title

• Should encapsulate the paper's main idea and include major variables.
• Must be concise while showing relationships among key variables.
• Should specify the participants involved in the study.

Title Elements

• Main Task
• Major Variables
• Topic
• Participants
• Setting
• Outcomes

Reminders for Title Creation

• Avoid using terms like "METHOD," "RESULT," or "INVESTIGATIONS."
• The general problem can serve as the thesis title when reformulated into a statement.
