Study Notes
Inquiry and Research Overview
- Research is derived from the French word "researchě," meaning "the act of searching closely."
- Leedy & Ormrod define research as the systematic process of collecting, analyzing, and interpreting information to enhance understanding of phenomena.
- Creswell characterizes research as the systematic and objective creation of knowledge.
Importance of Research
- Establishes knowledge and improves practices.
- Informs and contributes to policy-making.
- Solves problems by correcting perceptions and testing solutions for effectiveness.
Scientific Method Steps
- Empirical Approach: Gathering real-world data and metrics.
- Observation: Awareness of the environment forming ideas.
- Questioning: Formulating questions that require scientific investigation for tangible proof.
- Hypotheses: Educated guesses providing predictions about phenomena.
- Experiments: Hypotheses must be testable under controlled conditions.
- Analyses: Data analysis using statistical methods ensures reliability.
- Conclusions: Drawing inferences based on verified data, avoiding bias.
- Replication: Repeating studies with different participants for result validation.
Qualitative vs. Quantitative Research
-
Qualitative Research: Describes characteristics and quality of a subject while interpreting events.
- Strengths: Provides real experiences of individuals and allows in-depth responses.
- Weaknesses: Rarely uses statistical procedures and can be biased due to the researcher's subjective interpretation.
-
Quantitative Research: Tests hypotheses and makes predictions through numerical measurements.
- Utilizes statistical analysis for understanding data.
- Involves tools such as surveys and questionnaires for data collection.
Variables in Research
- Independent Variables: Manipulated to observe effects on dependent variables.
- Dependent Variables: Affected by changes in independent variables.
- Controlled Variables: Kept constant to ensure valid results.
- Confounding Variables: External factors that may affect the dependent variable but are not accounted for in the study.
Types of Variables
-
Categorical Variables: Describe quality and are divided into:
- Mutually Exclusive: Specific values without order (e.g., gender, civil status).
- Extensive: Ordered categories (e.g., size classifications).
-
Continuous Variables: Measured along a continuum (e.g., temperature range).
-
Quantitative Variables: Provide numerical details (e.g., levels of satisfaction).
-
Qualitative Variables: Represent types of objects and align with categorical variables.
Levels of Measurement
- Nominal Scales: Concerned with names and categories (e.g., nationality).
- Ordinal Scales: Rank data in sequential order (e.g., good, better, best).
- Interval Scales: Use equal units for measurement without a true zero (e.g., temperature).
- Ratio Scales: Highest level, includes a true zero (e.g., weight, height).
Importance of Studying Variables
- Enables proper interpretation of data.
- Assists in decisions on appropriate statistical analyses.
