On the other hand, longitudinal research observes variables for an extended period and records all the changes in their relationship. Whereas the cohort study is concerned with frequency of disease in exposed and non-exposed individuals, the case-control study is concerned with the frequency and amount of exposure in subjects with a specific disease (cases) and people without the disease (controls). Prospective A prospective study watches for outcomes, such as the development of a disease, during the study period and relates this to other factors such as suspected risk or protection factor(s). Qualitative is usually more subjective, although like quantitative research, it also uses a systematic approach. Sometimes exposure status is not clear when it is necessary to go back in time and use whatever data is available, especially because the data being used was not designed to answer a . You also have to thoroughly examine the source of the data given to you. The use of various psychedelic medicines appears to be associated with a broad range of qualitative experiences that could help clarify the mechanism of how they impact wellness in the future. You go ahead to recruit a set of newly-born lion cubs and study how they relate with each other as they grow. This type of study can provide important and unique perspectives and insights about certain topics. Qualitative research is generally preferred when the clinical question centers around life experiences or meaning. http://www.thejhs.org/article.asp?issn=2468-6360;year=2015;volume=3;issu http://www.fepto.com/wp-content/uploads/Hierarchy-of-Research-Design.pdf. This method of observation views research variables in terms of quantity hence; it is usually associated with values that can be counted such as age, weight, volume, and scale. In short, qualitative research helps us understand the why , how, or in what way behind a particular action or behavior. Quantitative is measurable.

Qualitative study generally falls under three types of designs: phenomenology, ethnography and grounded theory. Then, he conducts a baseline survey to establish the premise of the research for later comparison. Quantitative observation methods depend on fixed numerical parameters in order to categorize data samples while qualitative observation depends on subjective parameters for data gathering and, Quantitative observation methods depend on fixed numerical parameters in order to categorize data samples while qualitative observation depends on subjective parameters for data gathering and, Qualitative observation is more susceptible to. Longitudinal studies are primarily a qualitative research method because the researcher observes and records changes in variables over an extended period. Because of its focus on the in-depth description of research variables, qualitative observation is time-consuming, capital intensive and also requires a high level of expertise. In addition, qualitative studies often test a smaller sample size because of the costs and efforts associated with qualitative data collection methods.1. A longitudinal study can span weeks, months, years, or even decades. Birth cohort studies are a good example of prospective studies.
