Statistical Research Discussion
Given Inpatient Prospective Payment system Provider Summary (Data.CMS.gov, 2014), the data can be used to calculate the total amount of money spent on the medical cover per state. For instance, for the government to find out the medical expenditures and requirement for very state, total amount spent on medical cover per state may need to be calculated so that right measures may be taken based on the medical expenditure incurred. This may come in form of providing incentives to the hospitals or to the citizens indirectly; based on the need as ascertained by the expenditure. Having this kind of a problem, where we need total amount of medical cover per state, answers to descriptive quantitative questions can be used to solve the problem. For example, the questions can be:
How much money did New York Spent on medical cover?
Or generally, the question could be framed as
How much money was spent by each state on medical cover?
In this case, the independent variable is the state while the dependent variable is the amount of money spent by change state. This is basically because the amount of money may vary based on the state but not the other way round. The selection is based on the definition of what independent and dependent variables are. An independent variable is a variable in an experiment or a test that is changed, varied or controlled to test the effects on dependent variable. On the other hand, a dependent variable is a variable being determined (Helmenstine, 2017).
A confounding variable, also known as the third variable, is a variable that a researcher failed to curb hence damaging the outcome of the research (Shuttleworth). In this case, the magnitude, sensitivity, the seriousness or generally the cost of the medical case is one of the confounding variable. This is because if the cost of each case is not standardized, then there is probability that one state may have experienced a case that needed higher medical expenses hence its medical cover expenses higher. For example, if an accident had occurred in Illinois at the time when the records were taken and probably most of the victims who were seriously injured were covered and from the state, then Illinois may reflect higher medical cover expenses.
