Investigating background research in the area of interest, Identify how the theory will be tested and what the researcher expects to find based on relevant, previously published scientific works, to provide a summary of what the researcher is and how investigating a theory and what is expected to be found, to provide an answer to the research question, so that the hypothesis can be used for later data analysis, identify and operationalise the independent and dependent variable. A statistical hypothesis utilizes representative statistical models to draw conclusions about broader populations. There are requirements for the formulation of testable hypotheses. The hypothesis is the attempt to explain some phenomenon or problem that can be corroborated through observation or experimentation.
