Research Analysis Paper on Safety of Ultrasonography in Pregnancy

and fellow researchers in 2009 and published on electronic media-pubmed. Scientific research has immensely contributed to the medical field. Researches done in the past and in the recent times have employed proper scientific guidelines to ensure their validity in different contexts. Although it would be tempting to assume that all research available is done by qualified individuals hence is up to standard, some of them require a critical analysis to ascertain their validity. This paper analyses a research study by Allen T. and fellow researchers published in 2009 in pubmed. The paper first highlights the appropriate research methodology that is generally used and then gives a thorough critique of the study. It goes on to assess the validity of the research. Finally, the paper briefly discusses the various controversies on the question of the safety of an obstetric ultrasound and then gives a conclusive summarized critique of the study. In research, collection of data is an art and a key step that must be perfected. There are various methods that can be employed in data collection during research. In literature searches, the researcher collects documented information from various published literatures that include annual reports, journals, magazines, newspapers and online databases. Others include personal interviews, focused groups, email surveys etc. However, scientific research is done following strict research methods with specific guidelines. The basic elements of a research include validity, which is assessed by four different measures. An ideal research should have construct validity, statistical conclusion validity, internal and external validity. There are four types of research studies- observational research, correlation research, experimental research and quasi experiments. The five sampling techniques include convenience sampling, random simple sampling, systematic sampling, stratified sampling and cluster sampling (Dane, 2008) In this research study, the researcher collected information from internet databases by searching the various online databases. One notable undoing to this kind of technique is that it is more effective when the study parameter is not scientific. While the question in research is a science based question, the method of data collection does not follow the scientific research standards. Therefore the information collected is bound to have errors. In addition to that, the research does not give a working hypothesis. Any reader of the article fails to recognize the initial view of the person(s) doing the research. A good and measurable hypothesis helps elaborate the whole objective of the research. It would be expected that a hypothesis such as ‘’Obstetric ultrasound is safe to the mother and the fetus would give an insight into the objective of the research, as well as qualify the research as a question of real concern (Kothari, 2009). The research fails to highlight essential background information. A standard scientific research would no doubt in which it discusses the topic in research. It should have highlighted the controversies and uncertainties surrounding the use of obstetric ultrasound. Additionally, to bring to light the statistical facts involving on whom an obstetric ultrasound is performed in various countries. Of more help, also, would be highlight of the various national policies as far as obstetric
