Average length of stay

So far we have established some key information about total hospitals and discharges in the dataset, along with some interesting demographics on the patient profile.

Now it's time get calculating our first efficiency measure of interest, the average length of stay (LOS) days. Your task here will be to explore how LOS varies across some of demographics fields you have become familiar with.

We do not recommend doing so, but if you lost progress, you can load the solution workbook of the previous exercise 1_3_discharges_solution.twbx from the Workbooks folder.
