There is a severe shortage of critical care doctors and nurses to provide intensive-care services in hospitals. To offset this shortage, many hospitals, such as Emory Hospital in Atlanta, are using electronic intensive-care units (eICUs) to help provide this care to patients (Emory University News Center). eICUs use electronic monitoring tools and two-way communication through video and audio so that a centralized staff of specially trained doctors and nurses - who can be located as far away as Australia - can provide critical care services to patients located in remote hospitals without fully staffed ICUs. One of the most important metrics tracked by these eICUs is the time that a patient must wait for the first video interaction between the patient and the eICU staff. Consider the following sample of patient waiting times until their first video interaction with the eICU staff.

Step 1
For example, let's assume the sample data is as follows (in minutes): \[ 12, 15, 10, 20, 18, 25, 30, 22, 17, 14 \] Show more…

One of the most important metrics tracked by these eICUs is the time that a patient must wait for the first video interaction between the patient and the eICU staff. Suppose the following is a sample of 8 patient waiting times in minutes until their first video interaction with the eICU staff: 9, 100, 20, 10, 18, 8, 16, 8 Based on the data, which measure of variability would you emphasize most? a) median b) range c) standard deviation d) coefficient of variation e) Interquartile Range (IQR)
