Extracted text: Dr. Mason researched the relationship between listening to music and driving ability. She randomly assigned participants to either listen to music while driving or not listen to music while driving, and then tested driving ability by requiring participants to park in a small parking space in a crowded parking lot. Dr. Mason conducted the study across 2 weeks. Participants in Week 1 were assigned to not listen to music, and participants in Week 2 were assigned to listen to music while driving. Dr. Mason rented a car so that all participants could drive the same vehicle. However, Dr. Mason wasn't able to rent the same car in Week 1 and Week 2. She rented a smallI, compact car in Week 1, and a large SUV in Week 2. Results showed that participants who did not listen to music while driving had better driving ability compared to participants who listened to music (t(99) = 5.02, p<.05). what="" is="" a="" confounding="" variable="" in="" the="" above="" scenario?="" the="" type="" of="" car="" dr.="" mason="" listening="" to="" music="" driving="" experience="" and="" skill="" of="" participants="" o="">
