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.
