Quantity vs quality quantitative and qualitative are, importantly, words to describe the kind of data gleaned from an experiment and not the phenomena themselves the kind of data we extract from an experiment depends on the experiment design and the parameters we as researchers set before beginning. While defining quantitative and qualitative research based on their uses and purposes may be considered a practical approach for researcher, the difference actually lies on their roots: quality and quantity. Case studies using quantitative analysis contain elements of the empirical-analytical scientific approach these are often considered as opposing the dominant qualitative approach of case study research. Randomized controlled trials are considered the gold standard or best possible design (in quantitative research) you may also hear randomized controlled trails referred to as true experiments.
Therefore, as quantitative research is essentially about collecting numerical data to explain a particular phenomenon, particular questions seem imme- diately suited to being answered using quantitative methods. A mixed research design involves having both a quantitative design and qualitative design mixed designs is the best approach if the study requires both quantitative and qualitative designs to address the problem statement. The design can be used with both quantitative and qualitative methods rember that because of the differences between qualitative and quantitative research in philosophy, and the order in which steps are taken, the two studies would be very different.
