The research process begins and ends with the hypothesis. It is core to the entire procedure and, therefore, is of the utmost importance. A hypothesis can be formulated in several ways yet it always performs the basic function of predicting the final outcome of the investigation. The hypothesis usually occurs after inductive reasoning, in which the researcher performs a series of observations in order to form a theory. This hypothesis is then part of the first stage of the research process, of which there are 10 phases:

• Turn your ideas into a research question.
• Review the literature.
• Design the study and develop your method(s).
• Writing your research proposal.
• Issues about funding.
• Obtain ethical and trust approval.
• Collect and collate the data.
• Analyze the data and interpret findings.
• Implications of your research for clinical practice.
• Report on the study and disseminate the findings.

A hypothesis ensures the entire research process remains scientific and reliable, following the principles of deduction. The hypothetico-deductive model was first proposed by Karl Popper who suggested that theories about the world should come first and these should be used to generate hypothesis which can be falsified by the empirical data produced by observations and experiments.

Though hypotheses are essential during the research process, it can produce complications with regards to probability, significance and Type I -Type II errors. A Type I error occurs when p value is too large and the null hypothesis is falsely rejected and the research hypothesis is falsely accepted. A Type II error occurs when the researcher falsely accepts the null hypothesis and falsely rejects the research hypothesis as p value is too small. To confirm, a null hypothesis is only used with statistics and claims there is no variation or difference between variables.
