Question: Laparoscopic surgery is a procedure for threading a small flexible tube within a patient's body to explore or perform procedures. A recent study was conducted to see what skills a medical student new to laparoscopic surgery might have that would predict shorter learning times. One variable that was gathered was the amount of time a student had spent playing video games before starting his laparoscopic training. The researcher wants to see if the time spent gaming can predict the time needed to perfect laparoscopic skills. What would be the correct test to apply?
