Part One: Advocates of minimally invasive surgery (MIS) claim that patients experience more pain with traditional surgery which makes larger incisions than they do with MIS. To investigate this claim, a researcher collected data on patients who underwent cardiovascular surgery, half with traditional surgery and half with MIS. The data consisted of the reported pain level of each patient recorded 24 hours after surgery. The pain scale ranged from 1 to 10, with higher scores indicating more pain. Below are the scores for 15 patients who underwent traditional surgery.
