REC=subject number,
LOS=length of stay (days), DOC=physician, AGE=
patient age in
years
Create a frequency
distribution table for the LOS variable using the following four
class intervals: 7-8; 9-10; 11-12; 13-14. Calculate and include the
relative frequency of each class interval and include a TOTAL row
for reference.
2. You work with a small rural hospital. The hospital is losing nearly 50% on its Medicare patients due to extremely long length of stays (LOS). You randomly select 10 cases from each physician and collect information on LOS and age of patient. Your results are in Table 1 below.
