Question

A campus researcher wanted to investigate the factors that affect visitor travel time in a complex, multilevel building on campus. Specifically, he wanted to determine whether different building signs (building maps versus wall signage) affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building. Three subjects were assigned to each of the combinations of signs and starting locations, and travel time in seconds from beginning to destination was recorded. How should the data be analyzed? Starting Roonm Exterior 224, 339, 139 226, 129, 130 R1079-224, 339. 139 Wall Signs Map 141, 119,238 83, 94, 126 completely randomized design O B. randomized block design O C. 2 x 2 factorial design O D.
