Module 1.1: Qualitative vs Quantitative Research

Qualitative vs. Quantitative Research

• Quantitative Research

  • Utilizes objective, systematic empirical investigation.
  • Involves computational techniques applied to quantifiable data.
  • Focuses on numerical analysis to generalize findings to larger populations.
  • Concerned with measurable and countable variables.
  • Data primarily in numerical form, enabling statistical analysis.
  • Instruments used are structured and standardized.
  • Sample sizes are typically large (n>30).
  • Results are objective and can be generalized.
  • Employs statistical methodologies to quantify phenomena like attitudes and behaviors.
  • Allows for replicable studies through standardized approaches, enhancing validity.

• Qualitative Research

  • Aims to understand underlying reasons, opinions, and motivations.
  • Delves deeper into phenomena using words, perceptions, and feelings instead of numbers.
  • Often employs open-ended questionnaires to gather rich data.
  • Sample sizes are small (5-20 participants) and respondents are selected to meet specific quotas.
  • Research questions are well-defined to seek objective answers.
  • Data collection instruments are less structured and often exploratory.
  • Data is typically presented in the form of thematic analysis rather than numerical analysis.

Characteristics of Research Types

• Quantitative Research Characteristics

  • Objective measurement ensuring accurate results and analysis of concepts.
  • Research questions are clearly defined prior to data collection.
  • Data collection is guided by structured instruments promoting reliability and validity.
  • Summarized data presented through figures, tables, or graphs helps identify trends and relationships.
  • Preferably uses large sample sizes to ensure statistically valid results.
  • Random sampling is critical to eliminate researcher bias in data interpretation.
  • Findings can be replicated in different settings, reinforcing validity and reliability.

• Qualitative Research Characteristics

  • Focuses on gathering deep insights before concluding or solving problems.
  • Small sample sizes aimed at fulfilling specific quotas rather than generalization.
  • Relies on the richness of data from responses instead of statistical measures.
