Study Notes

Quantitative Methods

Emphasizes objective measurements and statistical analysis of data.
Data collected through polls, questionnaires, surveys, or manipulation of pre-existing statistics.

Focus of Quantitative Research

Aims to gather numerical data to generalize findings across groups or explain specific phenomena.

Key Characteristics

Large Sample Size: Enhanced generalizability of findings due to larger participant groups.
Measurability: Utilizes numerical data that can be easily analyzed and quantified.
Close-ended Questions: Allows for structured responses that can facilitate consistent data collection.
Reusability: Structured nature allows replication by other researchers, essential for verifying results and building knowledge.
Reliability: Reduces the impact of random variations through large samples and standardized instruments, yielding more reliable results.
No Research Bias: Facilitates objective findings by minimizing researcher bias and subjective interpretations.
Generalization: Findings are often intended to apply to a larger population, extending the relevance of results.
Prior Study Influence: Factors related to the research topic are examined before respondent feedback to inform outcomes.
Support for Previous Research: Results can contribute to previous studies, enhancing the understanding of the research topic.
