Study Notes

Nature of Inquiry and Research

Research involves systematic investigation to establish facts and strive for new conclusions, vital for academic and industry fields.
Qualitative research aims to explore meanings assigned to social or human problems by individuals or groups.
Quantitative research tests theories through the examination of relationships among variables, utilizing numerical data.
Mixed methods research combines both quantitative and qualitative data for a comprehensive approach.

Research Process Phases

Conceptualization phase: Identify a topic that is not too broad or too specific to allow for exploration.
Literature review: Required for quantitative studies; optional for qualitative inquiries.
Objective framing: Focus on central questions to understand human experience through qualitative data.
Design (planning) phase: Lays the framework for research methodology.
Empirical phase: Data gathering using interviews and focus groups, guided by interview protocols.
Analytical phase: Prepares and assesses data; applies tools for qualitative, quantitative, or mixed analysis.

Research Manuscript

Final output presented in written form, adhering to specific content guidelines.
Traditional format is chapter-based; modern formats often follow IMRAD structure based on APA standards.

Quantitative Research

Utilizes statistical, mathematical, or computational methods, presenting data numerically to uncover variable relationships.
Characteristics include a clearly defined research question, potential for generalization, structured data collection, and use of tools like questionnaires.

Advantages and Disadvantages of Quantitative Research

Advantages: Allows collection of large data sets, perceived as objective due to quantifiability, valuable for grants and proposals.
Disadvantages: Data analysis can require complex software, large samples increase analysis time, and may overlook human experiences.

Research Design in Quantitative Approach

Non-experimental design establishes associations without manipulating variables.
Experimental design establishes causality with manipulated variables.

Types of Experimental Research

True experimental research: Involves random assignment to control and experimental groups to explore cause-and-effect relationships.
Quasi-experimental research: Uses carefully selected groups instead of randomization due to practical or ethical constraints.

Non-Experimental Research Design

Survey research: Most common quantitative method, collects numerical descriptions of trends through questionnaires or interviews.
Types include cross-sectional (data at one point in time) and longitudinal (data over time).
Correlational research: Determines relationships between two variables within a single group.
Comparative research: Analyzes differences between variables without implying causation.

Research Methodology

Outlines methods used in research with the goal of enabling replication and evaluation.
Elements include research design (qualitative/quantitative), research setting (geographical characteristics), and research subjects (demographics and sampling procedures).

Understanding Sampling

Population: Entire group targeted for research.
Sample: Subset of the population selected for analysis; should closely approximate population characteristics.
Slovin's Formula: Used to calculate optimal sample size based on population size and margin of error.

Types of Non-Probability Sampling

Convenience sampling: Selection based on researcher's convenience, e.g., street interviews.
Purposive sampling: Selection based on specific criteria relevant to the study, carries a risk of researcher bias.
Quota sampling: Identifies population segments and specifies participant numbers needed from each.
Snowball sampling: Participants refer others who meet the criteria, assuming shared experiences among acquaintances.
