The main difference between qualitative and quantitative methods is flexibility. As a whole, quantitative methods have relative inflexibility. Qualitative methods are usually more flexible, allowing more naturalness and acclimatization for the interaction and collaboration between the researcher and the participant.
A truly important point in the comparison between quantitative research and qualitative research is that the subjective participation of the researcher -- that is one of the most resilient objections regarding qualitative research -- takes place in quantitative approaches.
