Quantitative Research Dissociates the Investigator from His “Biases”
1. Rule Out Chance2. Control for

Conclusion
• Qualitative + Quantitative = Mixed Methods• Qualitative: subjective, perspective dependent• Quantitative: objective, neutral view of truth• Mixed: Captures “Truth” both ways• Sequential or Concurrent• Full or Partial• Dominant or Non-dominant
