Data army - Essay ExampleData Collection using the phenomenological approach can take m any forms. The around commonly used is dialogue with open audiences. Methods of info collection could be written notes, video and auditory sensation recordings. Non verbal communication is body language which can be taken into account. These techniques are whateverwhat immanent this is because the principal aim here is to explore the problem and get a deeper understanding so that some hypothesis can be formulated. In an RCT, the interview has to be highly structured, because vicenary data has to be generated. In a structured interview, the questions have set answers, such as in multiple-choice questions, so that a limited choice is provided to the responder, and one question leads to another for example, if the answer to above question was Yes then please answer the next 3 questions. Unstructured questions are to a greater extent open-ended, allowing the responder a hand more leeway in ter ms of answers that he can provide in his/her own language. Further, as RCTs usually entail some form of intervention/procedure/treatment, there are many more potent means of data collection.In the example cited above, there can be two phases of data collection in the first phase, qualitative data can be obtained through unstructured interview of endoscopists to find out details about the two procedures (colonoscopy and double contrast barium enema) which can kick in the controversy that exists. However, the essential question as to which of the two modalities is most sensitive and specific, and therefore more reliable, requires quantitative data of the type obtained through RCTs. This depends on blinded observations by the endoscopists who initially perform colonscopy without knowing the results of the atomic number 56 studies if no polyp was demonstrate during colonoscopy, then the barium enema result was revealed to them, and if a polyp had been found in the latter, they re-exa mined the segment. Data collection here depends on highly structured and rigid enquiry of the endoscopists, and numeric data is generated. Compared to this the phenomenological approach to the interview is unstructured, flexible and open-ended, using audio tapes and verbatim reports so that more slender and in-depth, though descriptive information can be obtained. DATA ANALYSISData analysis is diverse in both methods. Among the many different means of analysing data available in phenomenological research, the method propounded by Glaser and Strauss (1967) is the one most utilised, namely the Grounded theory approach. Data from RCT is analysed statistically, whereas data from phenomenology is analysed for codes, themes and patterns for example in the study on double contrast enema, the initial phenomenological research data will be analysed to establish whether there is any pattern, or if a theory can be generated which can then be studied in the RCT phase. In RCT, data is analysed using tables and graphs, whereas in Phenomenology, data is analysed more subjectively. The theory generated in phenomenological research depends on, emerges from and is grounded in data, which is why it tends to be a cyclical process, as collection and analysis can go hand-in-hand, contrary in RCTs where data collection is based on decisions taken during the design stage, and analysis
