What is a qualitative experiment?
A qualitative experiment is an experiment that uses a qualitative technique to determine the truth of the tested hypothesis. Various different methods of qualitative research can be used, including case studies, interviews or diaries, and all are connected by being objectively structured methods of information collection. Scientists usually perform a qualitative experiment as a way of finding a better hypothesis for a quantitative experiment on a larger scale that can more effectively provide evidence for that idea or against this idea. Quantitative research is the most scientific design and generally concerns larger samples and the use of objective methods for record results. For example, a quantitative experiment can be carried out to determine the effectiveness of the diabetes drug by giving diabetics and taking insulin levels to see how effective treatment is. Qualitative experiment, on the other hand, would be something like a case study where one individual person who knows is observedThe state or effects of treatment. The use of quantitative methods is more convenient for scientists because it provides more opportunities to generalize the entire population.
Most often, the qualitative experiment will be used to obtain a general feeling for a specific area of research before the formulation of hypothesis, which can be tested on a larger scale in a quantitative study. Qualitative research is inherently defective because it looks only at a small population and the results cannot be recorded numerically, which means that unreliable human interpretation is the core of findings. This causes a problem if the researcher wanted to secure the whole population, because there are many different factors that could affect the results that are not properly controlled. The researcher may notice in the case study that the patient showed increased anger while taking one medicine but could wrongly combine both things and ignore something relevant as Je increased stress at work.
In a qualitative experiment, many different methods can be used, but case studies and interviews are the most common. These methods are characteristic of qualitative research, because through these methods it is difficult to study people in large numbers and the observations of the researcher are central to identify, even if they are contrary to the truth. On the other hand, qualitative experiments provide greater depth of understanding to a specific object and obtain a name from the “quality” of their findings. The use of qualitative and quantitative research methods can therefore be used to get deep understand the topic and then objectively test it.
