Research Question and Hypothesis
Research Question: Why do children from violent families exhibit PTSD?
Null Hypothesis: There is no significant relationship between children with PTSD and their family background.
Alternative Hypothesis : Children from violent family backgrounds are more likely to exhibit PTSD as opposed to children loving and peaceful families.
A hypothesis is a speculation based on insufficient evidence and information. A hypothesis can be proven either as true or false with further testing. A null hypothesis is a hypothesis that states that no relationship exists between two variables. A null hypothesis therefore seeks to disapprove a hypothesis. Null hypothesis is used when drawing conclusions from collected data by trying to disapprove a drawn hypothesis (Harrell, et al. 2016, 1051). The identified problem is identified in the research question that seeks to be answered. The relationship between the hypothesis to the identified problem is that a hypothesis seeks to identify the relationship between the variables in an identified problem. The problem of PTSD in children from violent families can only be understood by explaining the relationship between these two variables.
The hypothesis mentioned above is feasible because it is possible to assess the assumptions states through experimentation, observation, and experience. The ability to the hypothesis to be tested makes the conclusions drawn from the study to be based on scientific methods of assessment. The ability to test variables the most appropriate research method is the most recommendable ways to ensure the feasibility of hypothesis. From the above hypothesis, it is feasible to conduct a study on children from violent families and their behavioral and emotional outcomes later in life. On the other hand, the hypothesis is testable and measurable because real tests can be conducted on the variables to support or falsify a stated prediction. Furthermore, scientific methods of measurement can be used in to test the hypothesis (Mazzarell, et al. 2017).
