A very specific and useful presentation on the differences between quantitative and qualitative research, as well as a brief introduction to case studies.

2. Qualitative research explores attitudes, behaviors and experiences through such methods as interviews or focus groups. It attempts to get an in-depth opinion from participants. As it is attitudes, behavior and experiences which are important, fewer people take part in the research, but the contact with these people tends to last a lot longer. Under the umbrella of qualitative research there are many different methodologies.

4. Quantitative research generates statistics through the use of large-scale survey research, using methods such as questionnaires or structured interviews.
