Study Notes
Research Overview
- Research is a systematic process aimed at gathering, analyzing, and interpreting information to enhance understanding of a phenomenon.
- Two primary types of research: qualitative and quantitative.
Qualitative vs. Quantitative Research
-
Qualitative Research:
- Analyzes non-numeric data such as words, images, and objects.
- Primarily exploratory, focusing on discovering ideas or concepts.
- Hypotheses may be developed rather than tested.
- Involves small, individualized sampling.
- Utilizes open-ended instruments encouraging exploration.
-
Quantitative Research:
- Analyzes numeric data and statistics.
- Aims for conclusive results, examining relationships among variables.
- Involves testing hypotheses.
- Utilizes larger groups and random sampling methods.
- Employs close-ended instruments for specific data collection.
Characteristics of Research
- Objective data collection and analysis, minimizing researcher bias.
Variables in Research
-
General Definition: Variables represent components of interest like people, places, or phenomena that can be quantified.
-
Experimental Variables:
- Independent Variable (IV): Controlled and manipulated by the researcher.
- Dependent Variable (DV): Changes as a result of manipulating the IV.
- Intervening Variable: Hypothetical links between variables, not directly observable.
- Confounding Variable: Influences both IV and DV.
-
Non-Experimental Variables:
- Predictor: Used to forecast an outcome.
- Criterion: Often synonymous with the dependent variable in non-experimental settings.
Types of Variables
-
Categorical Variables:
- Nominal: Categorized without order (e.g., blood type).
- Ordinal: Ordered classifications without a strict hierarchy (e.g., socioeconomic status).
- Dichotomous: Two categories (e.g., gender).
-
Continuous Variables:
- Interval: Quantified along a spectrum with meaningful distances (e.g., temperature).
- Ratio: Similar to interval but includes a true zero point (e.g., weight).
Research Designs
- Experimental Group: Receives the treatment or variable.
- Control Group: Does not receive the treatment.
- True Experimental Research: Randomly assigns participants to groups to study cause-and-effect.
- Quasi-Experimental Research: Non-random groups are used to explore causal relationships.
Hypothesis in Research
- Defined as a tentative explanation that links variables; tested through investigation.
- Null Hypothesis (Ho): No relationship between variables.
- Alternative Hypothesis (Hi): Indicates a relationship exists.
Crafting Effective Research Titles
- Titles should be phrase-like with at least 12 substantive words.
- Indicate key factors such as IV, DV, and target population.
- Aim for clarity and attractiveness while adhering to the SMART criteria.
Background of the Study
- Highlights the topic's nature, justifies the study, and addresses trends, issues, objectives, and overall contributions to knowledge.
Research Problem and Statement
- Identifies areas of concern and challenging questions derived from literature or theory.
- Clearly articulated statements of the problem identify key objectives and methodology.
Research Question Structure
- Choose the type of question (descriptive, comparative, relationship).
- Define the variables for measurement.
- Write a complete research question addressing specific issues.
Literature Review
- Review of Related Literature (RRL) examines connected works.
- Paraphrasing involves rephrasing ideas without losing meaning.
- Summarizing distills key points from material.
Scope and Delimitation
- Scope: Defines the study's parameters, including demographics and temporal boundaries.
- Limitations: Internal weaknesses beyond the researcher’s control.
- Delimitation: Clearly outlines the parameters set by the researcher.
Conceptual Framework
- Visual representation of the relationships between variables, indicating correlation and influence.
- Arrows indicate causation; lines denote correlation without direct causation.
