Quantitative vs Qualitative Research

Introduction

• Presenter: Jessica from Scribbr
• Overview: Differences between quantitative and qualitative research

Quantitative Research

• Purpose: Test hypotheses
• Data: Expressed in numbers and graphs
• Sample Size: Larger
• Analysis: Math and statistical analysis

Qualitative Research

• Purpose: Formulate hypotheses
• Data: Expressed in words
• Sample Size: Fewer respondents
• Analysis: Summarizing, categorizing, and interpreting

When to Use Each Approach

• Quantitative: To confirm or test theories/hypotheses
• Qualitative: To understand or explore ideas
• Mixed Method: Combines both approaches
  • Example: Satisfaction among students
    • Quantitative: Survey 300 students, rate satisfaction on a scale
    • Qualitative: Interview 15 students with open-ended questions
    • Mixed Method: Conduct interviews to formulate hypotheses, then survey to test on a larger scale, or vice versa

  • Surveys (online, in person, over the phone)
