Study Notes

Future Outcomes

Researchers define clear objectives before collecting data, ensuring well-structured questions for quantifiable results.
Advanced mathematical modeling and computer simulations create if-then scenarios that predict future outcomes.

Quantitative Research

Emphasizes proof and validation rather than exploration, with a focus on measurable evidence.
Utilizes standardized research instruments, such as questionnaires, for accurate data collection.
Data collected includes measurable population characteristics, e.g., age, socio-economic status, number of children.
Larger sample sizes enhance the reliability and validity of results, allowing for more dependable conclusions.

Strengths and Weaknesses of Structured Research Instruments

Standardized tools ensure accuracy and validity throughout the research process.
Quantitative research results can generally be generalized to larger populations, but may miss deeper contextual insights.

Types of Variables

Variables are used in models to represent observable events and provide broad contexts for analysis.
The design evolves and adjusts as the study develops, focusing on clearly defined variables.

Advantages of Quantitative Research

Provides numerical data that can be statistically analyzed, facilitating hypothesis testing.
Results often lead to the formation of new hypotheses or disproving existing ones.
Offers larger sample sizes which contribute to more generalizable findings.

Limitations of Quantitative Research

May not capture the complexity of human experiences or perceptions.
Statistical methods highlight outcomes but may not explain underlying reasons or contextual factors.
Risks presenting an inaccurate view of heterogeneity within the sample.

Qualitative Research

Provides rich, detailed insights into human experiences, albeit typically less generalizable due to small sample sizes.
Findings are subjectively interpreted, making them less standardized compared to quantitative methods.

Research Designs

Descriptive Research aims to understand the current state of a variable and answers what, where, when, and how.
Causal-Comparative (Quasi-Experimental) Research identifies how different groups are affected by the same circumstances, particularly useful when experimental research is not feasible or ethical.
