Research Methods: Qualitative vs Quantitative

Qualitative Vs Quantitative Research

Definition

• Qualitative Research: Focuses on gathering non-numerical data to gain a deeper understanding of attitudes, opinions, and behaviors. It involves collecting and analyzing text, images, and observations to identify patterns and themes.
• Quantitative Research: Involves collecting and analyzing numerical data to identify patterns and trends. It focuses on measuring and quantifying variables to test hypotheses and theories.

Key Characteristics

Qualitative Research

• Subjective: Interprets and analyzes non-numerical data
• Exploratory: Explores attitudes, opinions, and behaviors
• In-depth: Provides rich, detailed insights
• Small sample size: Often uses small, purposeful samples
• Data collection: Interviews, focus groups, observations, and content analysis

Quantitative Research

• Objective: Analyzes numerical data to identify patterns and trends
• Confirmatory: Tests hypotheses and theories
• Large sample size: Typically uses large, random samples
• Data collection: Surveys, experiments, and secondary data analysis

Strengths and Limitations

Qualitative Research

• Strengths:
  • Rich, in-depth insights
  • Exploratory nature allows for discovery
  • Flexibility in data collection and analysis
• Limitations:
  • Subjective interpretation
  • Small sample size limits generalizability
  • Time-consuming and resource-intensive

Quantitative Research

• Strengths:
  • Objective analysis
  • Large sample sizes enable generalizability
  • Precise and reliable results
• Limitations:
  • Limited depth of insight
  • Risk of oversimplification
  • Depends on high-quality data collection

When to Use Each

• Qualitative Research: Use when exploring attitudes, opinions, and behaviors; when seeking in-depth insights; or when developing hypotheses.
• Quantitative Research: Use when testing hypotheses; when analyzing large datasets; or when seeking to generalize findings to a larger population.

Key Characteristics

Qualitative Research

• Interpretive and subjective, involving non-numerical data analysis.
• Exploratory in nature, aiming to understand attitudes, opinions, and behaviors.
• Provides in-depth insights, with a focus on quality over quantity.
• Typically uses small, purposeful samples.
• Data collection methods include interviews, focus groups, observations, and content analysis.
