According to Graham Horton, “the whole point of doing on experiments is to test a hypothesis because without hypothesis you wouldn't know what experiment to carry out". (Horton 2010) It is all about experiences, insight intuition, analogy and extrapolation. Hypothesis deals with data collection, the pattern of data which involves explanation. Hypothesis has to be tested with more data to see if there is continuation of the pattern otherwise the hypothesis has to be changed since that data didn't support that hypothesis cannot be called scientific unless it can be supported or refuted with something.
Clearly, a working hypothesis must have sufficient data and evidence to support that hypothesis. Shawn McCaslin said that if performing scientific experiment hypothesis are not necessarily required. He went further to explain that hypothesis when dealing with existence is not required (Shawn, 2016).
In science hypothesis is very much a misunderstanding concept. Exploratory research is a research that is conducted for a problem that has not been clearly defined. Therefore hypothesis is not necessary for exploratory research. In other words not all research projects need to be directed by a hypothesis.

Explain why it is necessary to have a clearly stated hypothesis before beginning to collect data. A hypothesis is necessary because, “The primary research question should be driven by the hypothesis rather than the data”( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2912019/). Before the start of any research the research question and hypothesis should be developed. Failure to do so could result in counter productivity for the researcher . In this case the researcher must work backwards using the data for the purpose of developing the “question.” So this doesnt make much sense, because the question (hypothesis) is asked to assist the researcher with finding the answer. A good hypothesis is based on a good research question which then drives data collection for the study. An example of a good hypothesis is provided by a article “in a research study comparing computer-assisted acetabular component insertion versus freehand acetabular component placement in patients in need of total hip arthroplasty, the experimental group would be computer-assisted insertion and the control/conventional group would be free-hand placement. The investigative team would first state a research hypothesis. This could be expressed as a single outcome (e.g., computer-assisted acetabular component placement leads to improved functional outcome) or potentially as a complex/composite outcome; that is, more than one outcome (e.g., computer-assisted acetabular component placement leads to both improved radiographic cup placement and improved functional outcome)” ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2912019/). If a hypothesis is written correctly it will support good research query and also have an influence on the remainder of the research design. The ability to ask good questions that lead to great research, are ultimately determine the outcome of a study.Explain why it is or why it is not necessary for all research projects to be directed by a hypothesis. According to the research article it is possible that a study that is comprised of “Multiple statistical testing of associations from data previously collected” could yeild favorable results. But this is not always the case. Please keep in mind that all research is not validated and that it is important to retest, experiment or independantly analyze data before summarizing your findings.
