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.
