What is the main difference between qualitative and quantitative methods regarding sampling approaches?
- Qualitative methods rely on random sampling, while quantitative methods focus on purposeful selection of small samples.
- Qualitative methods focus on in-depth study of small purposefully selected samples, while quantitative methods depend on larger randomly selected samples. (correct)
