Practical Research 2: Intro to Quantitative Research

Introduction to Quantitative Research

• Quantitative research focuses on gathering numerical data to explain phenomena and generalize findings across groups.
• Clearly defined research questions are fundamental to the approach.
• Structured research instruments are employed to ensure consistency in data collection.

Characteristics of Quantitative Research

• Objective in nature, avoiding subjective interpretations.
• Data is presented numerically, facilitating statistical analysis.
• Large sample sizes enhance the reliability of results and conclusions.
• Research can be replicated across different contexts to confirm findings.
• Data analysis can predict future outcomes and verify existing information.
• Capable of developing new concepts based on analyzed data.

Strengths of Quantitative Research

• Objective data minimizes misinterpretation, making findings result-based.
• Statistical techniques allow for sophisticated analyses of large datasets.
• Quick and efficient analysis through valid random sampling enables generalization to populations.
• The ability to replicate research enhances validation across different settings and conditions.
• Data collection tools like questionnaires streamline the process, allowing for swift data gathering.

Weaknesses of Quantitative Research

• Requires a large respondent base, increasing the complexity and difficulty of data collection.
• Associated costs rise with larger sample sizes and extensive distribution of research instruments.
• Lacks the ability to provide contextual elaboration, focusing instead on direct responses.
• Poorly designed questionnaires can yield invalid data, impacting the study's integrity.
• Researchers must be vigilant against respondents providing random guesses, which can skew results.
• Time-intensive preparation and validation of research instruments may delay the research process if no standardized tools exist.

Types of Quantitative Research

• Non-Experimental Research:
  • Descriptive Research: Describes characteristics of a population or phenomenon without manipulation.
    • Examples include studies on factors affecting academic performance, internet usage, and health practices.
  • Correlational Research: Examines relationships between two or more variables without interference from the researcher.
    • Examples include links between study habits and academic performance, exercise frequency and academic achievement, and attendance and success in school.
• Experimental Research:
  • True Experimental: Involves manipulation and control of variables for cause-and-effect relationships.
  • Quasi-Experimental: Similar to true experiments but lacks random assignment to treatment groups.
