use of antibiotics with MRSA occurred in only a small proportion of patients. This was an important,

assuming that the clusters are Interval data

We use data from the National Inpatient Sample. We want to see if we can use treatment choices to find
those with higher risk of infection compared to other treatments. Table 20 gives the 20 most frequent
