    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.
