Study Notes
Research Methods
- Statistical analysis identifies correlations, e.g., study time impact on academic performance.
- Experimental research examines cause-and-effect via controlled variables, e.g., assessing new teaching methods on performance.
Variables in Research
- Dependent Variable: The effect measured in a study, influenced by the independent variable; e.g., test scores indicate the effect of study time.
- Independent Variable: Manipulated by researchers to observe its effect; e.g., study time influences test scores.
- Extraneous Variables: Uncontrolled variables that may affect results; e.g., prior knowledge, sleep quality, and test anxiety.
Types of Quantitative and Qualitative Variables
- Discrete Variables: Finite and countable; e.g., number of students in a class.
- Continuous Variables: Infinite values within a range; e.g., height, weight.
- Ratio Variables: True zero points allowing for ratio calculations; e.g., age, income.
- Interval Variables: Equal intervals but no true zero; e.g., temperature in Celsius.
- Nominal Variables: Categorized without specific order; e.g., gender, race.
- Ordinal Variables: Categorized with a specific order; e.g., rankings.
- Dichotomous Variables: Two categories; e.g., Yes/No.
Guidelines for Writing a Good Research Title
- Must be concise and descriptive of the study.
- Should reflect key variables being examined.
- Avoid jargon with clear, simple language for accessibility.
Definition and Characteristics of Quantitative Research
- Quantitative research systematically quantifies relationships and phenomena via numerical data collection and analysis.
- Characterized by objectivity, systematic processes, replicability, measurability, large sample sizes, and statistical analysis.
Strengths and Weaknesses of Quantitative Research
- Strengths: Generalizable findings, high reliability, precision, minimized researcher bias, and comparability.
- Weaknesses: Lack of contextual depth, inflexible structure, limited scope on qualitative data, and can be resource-intensive.
Types of Quantitative Research Design
- Descriptive Research: Describes population characteristics using surveys and observational methods.
- Ex Post Facto Research: Investigates cause-effect through retrospective analysis of existing conditions.
- Correlational Research: Examines relationships among variables.
Background of the Study
- Introduces the topic, context, and reviews existing literature to identify key studies, theoretical frameworks, and research gaps.
- Importance of the research is articulated, alongside preliminary data if available.
Problem Statement
- Clearly defines the research problem within existing contexts and highlights its significance.
- Forms specific research questions, including primary and secondary questions to guide the investigation.
Objectives of the Study
- General objective outlines overall research goals, while specific objectives break them down into measurable SMART objectives, e.g., study habits' impact on performance.
Conceptual Framework
- Represents expected relationships between independent, dependent, mediating, and moderating variables through diagrams and explanations.
- Hypotheses are formulated based on the relationships defined.
Scope and Delimitation
- Scope: Defines the study's coverage, participant characteristics, variables, and methods used.
- Delimitation: Identifies boundaries, acknowledges limitations, states assumptions, and justifies exclusions.
Significance of the Study
- Research aims to contribute to knowledge, with practical implications for educational practices or policies and potential beneficiaries.
- Discusses social impacts and suggests directions for future research.
