Question
Understanding demand is always a key issue in business operations. The Hospital.csv contains Singaporeans’ arrivals at the major public hospitals’ emergency departments (EDs) in 2011. To make a staffing plan, which decides the number of nurses and doctors to serve patients, the intra- and inter-day variations in patient arrivals are important descriptive statistics. Please answer the following questions: (a) What is the patient arrival pattern within a day? Please draw a proper chart to present your findings. To answer this question, you should divide each day into 24 time intervals (each interval is an hour) and then find out the average number of patient arrivals in an interval. Moreover, you should assume there is no inter-day variability to find the average in part (a). Specifically, you should first create a 31 by 24 table to store the counting results. The first row of the table will be patient arrivals on Oct 01, 2011, in different time periods, say 12 midnight to 1am, 1am to 2am and so on. Then, collapse your rows to have 24 averages and each average represents the average hourly patient arrivals in that time period and visualize your findings.

Explanation / Answer
The question asks us to determine the patient arrival pattern within a day in a major public hospital's emergency department in 2011.

To depict the average pattern, we can use the below table showing the necessary information:
The above study shows that the pattern of patient arrival is varied dependent on various factors. Such factors include the time of the day during which patients are admitted, any mishappenings in the city, various communicable diseases etc.
