Study Notes

Characteristics of Quantitative Research

Emphasizes numerical data and statistical analysis to uncover patterns.
Aims to find generalizable truths through structured methodologies.
Primarily uses surveys and questionnaires for data collection.

Research Design Types

Non-Experimental Research Design:
- Focuses on describing associations between variables without manipulation.
- Suitable for evaluating marketing, social behaviors, and environmental factors affecting students.
Experimental Research Design:
- Investigates cause-and-effect relationships using manipulation of independent variables.
- Requires a control group and random assignment of participants to minimize bias.

Non-Experimental Research

Explores various variables without establishing causation.
Commonly utilized to assess social media impact, academic performance, and anxiety levels.
