Considerable Variables
Determining the variables to be used in testing the hypothesis constitutes segmentation of the dependent and independent variables. For this study, the independent variables are factors that can be observed, which provides the anticipated outcome of the study. In terms of identifying the effects if traumatic brain injury to behavioral change encompasses the need to look into an important set of variables. Factors such as injury proportion to the general population, age and sex are variables to the study that only be observed and quantified, but can be manipulated in order to test the probability of the given hypothesis. For example, the data presented in Faul et al., (2006) report suggests that TBI cases are more apparent among the make gender, encompassing a 50% difference as compared to female. The determinations of such findings were based on the factors, which are identified as the dependent variables. Another striking comparison was made between children and older adults. The data from Faul et al. suggests that there is 200% likelihood that children may TBI as compared to older adults. Therefore, the anticipation of the gap in terms of TBI occurrences between genders and age groups was observes based on the pre-determined set of dependent variables.
The relative factors that points out the difference on the number of TBI cases between gender and age groups is identified as causal factors in which the dependent variables are based from. For this study, the dependent variables are the causes of TBI cases across all the subjects of the study. Factors such as falling from heights, being struck by or against, other unknown external factors, motor vehicles or traffic related activities and assault are the dependent variables. Since dependent variables are by nature can be manipulated, the outcome of the findings can therefore be determined to align with the given hypothesis in the study. Eliminating or altering the predetermined causes of TBI among male subject can manipulate the number of male TBI case pertaining to vehicular causes. Dependent and independent variables mentioned herewith are the key factors that will be used to test hypothesis of this study.
