Counting vs. Understanding
Psychological research divides into two traditions. Quantitative research collects numerical data for statistical analysis, typically using larger samples to test hypotheses and generalize findings, like surveying 500 people for anxiety scores.
Qualitative research collects non-numerical data like interview transcripts and field notes using smaller samples. Its goal is exploring phenomena in rich contextual depth, such as interviewing chronic illness patients about their lived experiences.
| Feature | Quantitative | Qualitative |
|---|---|---|
| Data | Numerical | Non-numerical |
| Sample | Larger | Smaller |
| Goal | Test & generalize | Explore depth |
| Analysis | Statistics | Thematic |
Choosing the Method
Neither approach is superior; they answer different questions. Quantitative asks "how much" or "how strongly related," while qualitative asks "what is this experience like" or "how do people make sense of this."
Mixed-methods research combines both in one study, using a survey for breadth and interviews for depth.
Common pitfall: assuming qualitative research is "less rigorous" because it lacks numbers. It has its own standards like systematic coding and checking bias, trading statistical generalizability for crucial nuance.
