requires additional costs. To this end we may argue that most likely we will
need to consider further parameters in characterizing Clinics. Instead of
focusing on setting more appropriate control limits we intend to show that
data driven decisions could be more appropriate for this purpose. In what
follows, we present an explanatory analysis of the dataset at hand followed by
the proposed scheme for analysis.
To begin with in Figure 1 we illustrate the average expenditure for each
individual Clinic at the corresponding boxplot. It is evident that one can
identify significant variations between the Clinics. In addition, it is interesting
to examine the total count of incidents that each Clinic had to deal with during
this period of time (see Figure 2). As expected, we also identify significant
variation in this case. Finally, in Figure 3 we can see the total expenditure per
Clinic.
To this end, we can gather information from the aforementioned statistics
to create a dataset and the corresponding variables are the mean and standard
