Qualitative research is information that is gathered from interviews, sending out questionaires (if its not a questionaire with simple yes or no questions, as long as it has the answer then an oppinion), surveys ect.
Quantitative research is infomation that is presented as facts, statistics, percentages ect. Depending on what the source is, this is the more reliable of the two.
The 2004 american documentary "Supersize me" is a good example of both research techniques, at the begining of the film Morgan Spurlock talking with his personal trainer, he states that Morgan is above average phsyical shape and is healthy. He is then seen by three doctors a cardiologist a gastroenterologist and a general practitioner, as well as a nutritionist. All of the health profesionals predict that the diet will have an unwelcome effect on his body, but none of them expect anything too drastic one of them even saying the human body is very adaptable. All this research is done before hand and does not involve number this involves talking to the specialist and seeing what they think will happen. Therefore the beggining is Qualitative. Though as the documentary goes on more figures and statistics are shown giving a good mixture of Quantitative and Qualitative research.
