To improve efficiencies a hospital must analyze how often a surgery is started late by operating room and surgeon. The business analyst must consider several factors:
•Dates of each surgery
•Number of minutes the start of the surgery is delayed
•Operating room
•Surgeon name
Which visualization should the business analyst use to meet these requirements?
- A combo chart that shows total minutes of delayed starts by operating room and surgeon
- A bar chart with total minutes of delayed starts and a drill-down from operating room to surgeon
- A scatter plot with delayed start minutes per day operating room and surgeon
- A line chart with total minutes of delayed starts and a drill-down from operating room to surgeon
