Questions and Answers

What is a key characteristic of quantitative research?

  • It focuses solely on qualitative observations.

    Study Notes

    Nature of Quantitative Research

    Characteristics

    • Reliable and objective measurement of data.
    • Employs statistical methods for generalizing findings.
    • Simplifies complex issues into a limited number of variables.
    • Analyzes relationships between variables to determine cause and effect.
    • Tests theories or hypotheses through structured research.
    • Assumes representative sampling from a larger population.
    • Minimizes subjectivity in research methodology.
    • Focuses on specific details of the subject being studied.

    Disadvantages

    • Ignores contextual elements and natural settings of the study.
    • Requires larger sample sizes, which increases research resource demands.
    • Results are often constrained by numerical analysis, lacking depth in human narratives.
    • Provides less detailed accounts of participant perceptions and experiences.
    • Experimental control may not mirror real-world applicability due to lab settings.
    • Fixed-response formats may not accurately capture participant perspectives.
    • Researcher bias can inadvertently influence findings.

    Importance of Quantitative Research in Various Fields

    • Education: Measures performance levels in students and teachers; assesses the effectiveness of instructional methods and educational programs.
    • Business: Enhances marketing strategies; supports informed decision-making for product and service promotion.
    • Medical and Health Care: Produces statistics that can improve patient recovery rates and evaluate medication and vaccine efficacy.
    • Sciences: Ensures responsible and accountable technological operations during experiments.

    Classifications of Variables

    Numeric Variables

    • Continuous Variables: Allow any value within a range. Examples include time, age, and temperature.
    • Discrete Variables: Only take whole number values. Examples include counts of registered cars or students.

    Categorical Variables

    • Ordinal Variables: Can be logically ordered or ranked. Examples include academic grades and clothing sizes.
    • Nominal Variables: No inherent order. Examples include business types and eye colors.
    • Dichotomous Variables: Only two categories, such as gender or yes/no responses.
    • Polychotomous Variables: Multiple categories exist, such as levels of educational attainment.

    Research Title Guidelines

    • Should encapsulate the main idea of the research.
    • Must be concise and reflect the primary topic.
    • Include major variables and their relationships.
    • Clearly denote the task related to the main variables.
    • Specify participants involved in the study.

    Elements of a Research Title

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

    Title Composition Reminders

    • Avoid including terms such as "METHOD," "RESULT," or "INVESTIGATIONS."
    • The general problem can serve as a thesis title when articulated as a declarative statement.
