Study Notes

Concepts in Research

Concepts are building blocks of theory and research, representing abstract ideas generalizing observed behaviors.
Simplify the research process by categorizing characteristics or behaviors, making it easier for researchers to identify general patterns.
Facilitate communication among researchers by providing shared understanding—example: agenda setting.
Examples include advertising effectiveness, media usage, satisfaction, and patterns of behavior.

Constructs

Constructs are advanced concepts created for specific scientific purposes, combining various concepts that may not be directly observable.
Introduced by Wimmer & Dominick as tailored for particular research contexts, reflecting deeper meanings.
Utilize independent (e.g., smoking) and dependent variables (e.g., cancer) along with extraneous variables (e.g., age, dietary habits).

Measurement

Measurement involves determining the dimensions or values of phenomena by assigning numbers using predefined rules.
Key points in measurement include: numerals representing phenomena, assignment of numbers, and the importance of rules for consistency.

Levels of Measurement

Four main levels categorize data:
- Nominal Level: Simplest level, categorizes without quantitative value, ensuring categories are mutually exclusive and exhaustive without inherent order.
- Examples include caregiver assessments and techniques such as qualitative research for emotional depth.

Advantages and Disadvantages of Qualitative Research

Advantages:
- Provides natural context for behavior observation, enhancing understanding of unexplored phenomena.
- Flexible, allowing exploration of new interests through open-ended discussions.
Disadvantages:
- Small sample sizes limit generalization, potentially undermining reliability.
- Observer bias can influence objectivity, leading to skewed data if not well-structured.

Advantages and Disadvantages of Quantitative Research

Advantages:
- Numeric data allows for precision in reporting results and supports rigorous statistical analysis.
Disadvantages:
- Research settings can be artificial, affecting authenticity; survey respondents may provide misleading responses.

Mixed Methods Research

Combines qualitative and quantitative approaches to give a comprehensive understanding of research problems.
Known as triangulation, it integrates both methodologies to leverage their strengths in a single study.
Enhances the researcher's findings by allowing qualitative insights to inform quantitative data analysis or vice versa.
